The aims of the present study were threefold. First, optical indices of clear PMMA were determined from reflectivity and transmissivity measurements. Clear PMMA exhibits a strong non-grey behavior, quite transparent in the visible and near infrared ranges of the spectrum, and almost opaque in some bands of the mid infrared. Absorption and refraction indices were obtained using an identification method applied to the transmissivity data of several samples with different thicknesses whenever possible (i.e. in ranges with sufficiently high transmission levels), whereas elsewhere, the Lorentz oscillators model coupled with a genetic algorithm was applied to the reflectivity data. Secondly, the absorption coefficient was determined at a very fine resolution of 4 cm À1 . A nineteen-band model was proposed to represent the spectral variation of the absorption coefficient in the range of [590e18999 cm À1 ]. Third, a reciprocal Monte Carlo simulation was performed to calculate the response of a 3-cm-thick PMMA sample to a 18 kW m À2 externally incident radiation, involving absorption and internal emission into the solid. Radiative transfer, pure or combined with conduction and convection, was considered to simulate the early stages of sample heating (before the glass transition of PMMA) from two different radiative sources, namely a cone calorimeter and a tungsten lamp. The influence of the type of the radiation source was clearly demonstrated in terms of temperature distribution inside the material and divergence of the radiative flux.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/23475092" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="59fc2a7feaf38dfed8a0416cbce322ff" rel="nofollow" data-download="{"attachment_id":43912729,"asset_id":23475092,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/43912729/download_file?st=MTczOTgxNzcyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="45407807" href="https://independent.academia.edu/BPorterie">B.

The aims of the present study were threefold. First, optical indices of clear PMMA were determined from reflectivity and transmissivity measurements. Clear PMMA exhibits a strong non-grey behavior, quite transparent in the visible and near infrared ranges of the spectrum, and almost opaque in some bands of the mid infrared. Absorption and refraction indices were obtained using an identification method applied to the transmissivity data of several samples with different thicknesses whenever possible (i.e. in ranges with sufficiently high transmission levels), whereas elsewhere, the Lorentz oscillators model coupled with a genetic algorithm was applied to the reflectivity data. Secondly, the absorption coefficient was determined at a very fine resolution of 4 cm À1 . A nineteen-band model was proposed to represent the spectral variation of the absorption coefficient in the range of [590e18999 cm À1 ]. Third, a reciprocal Monte Carlo simulation was performed to calculate the response of a 3-cm-thick PMMA sample to a 18 kW m À2 externally incident radiation, involving absorption and internal emission into the solid. Radiative transfer, pure or combined with conduction and convection, was considered to simulate the early stages of sample heating (before the glass transition of PMMA) from two different radiative sources, namely a cone calorimeter and a tungsten lamp. The influence of the type of the radiation source was clearly demonstrated in terms of temperature distribution inside the material and divergence of the radiative flux.","downloadable_attachments":[{"id":43912729,"asset_id":23475092,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":45407807,"first_name":"B.","last_name":"Porterie","domain_name":"independent","page_name":"BPorterie","display_name":"B.

Higher Peclet numbers and shorter plug length result in higher Nusselt numbers and lower maximum fluid temperature.

The heat transfer in liquid plugs moving in microcapillaries with constant-surface-heat-flux boundary condition is investigated. The effects of the Peclet number and the plug length are studied. Higher Peclet numbers and shorter plug length result in higher Nusselt numbers and lower maximum fluid temperature. However, higher Peclet numbers require higher flow speed, while shorter plug lengths result in higher flow resistance coefficients. The pressure drop needs to be considered in the optimization of microchannel heat exchangers.","downloadable_attachments":[{"id":46279403,"asset_id":25918845,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":49712701,"first_name":"Zhizhao","last_name":"Che","domain_name":"tju","page_name":"ZhizhaoChe","display_name":"Zhizhao Che","profile_url":"https://tju.academia.edu/ZhizhaoChe?f_ri=187812","photo":"https://0.academia-photos.com/49712701/14264703/15220884/s65_zhizhao.che.jpg"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=187812","nofollow":true},{"id":305,"name":"Applied Mathematics","url":"https://www.academia.edu/Documents/in/Applied_Mathematics?f_ri=187812","nofollow":true},{"id":187812,"name":"Thermal Sciences","url":"https://www.academia.edu/Documents/in/Thermal_Sciences?f_ri=187812","nofollow":true},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering?f_ri=187812","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_69165347" data-work_id="69165347" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/69165347/Modelling_of_roughness_effects_on_heat_transfer_in_thermally_fully_developed_laminar_flows_through_microchannels">Modelling of roughness effects on heat transfer in thermally fully-developed laminar flows through microchannels</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">In this paper, roughness was modelled as a pattern of parallelepipedic elements of height k periodically distributed on the plane walls of a microchannel of height H and of infinite span.

Yet, the refrigerators commonly used for this purpose have improvable efficiency levels. Their performance, as shown by the literature, is highly influenced by the size of the heat exchangers and by internal irreversibilities. In this paper the maximum coefficient of performance (COP) is obtained for an irreversible inverse Rankine cycle refrigerator working with the environmentally friendly fluid R134a. This is a steady-state refrigerator working as an open system which consumes external work, subtracts heat from a cold fluid stream at an inlet fixed temperature and assigns it to a higher fixed inlet temperature stream. Heat transfer irreversibilities in the shell-and-tube heat exchangers and external friction losses in the water streams are considered, ignoring only the internal pressure drop of vapor. A simulation program was developed to search the maximum COP at given external fluid temperatures, as a function of mass flows, dimensions and temperature differences in the heat exchangers. Owing to the large number of control variables involved, a numerical optimisation method was used to determine the maximum COP. The proposed method is fast, producing the maximum with acceptable approximation. It provides the refrigerating fluid evaporating and condensing pressures, the heat exchanger dimensions, and the water flow rates for a given cooling power with predefined inlet temperatures of cold and hot water streams. The heat exchanger area closely conditions the COP, so each maximum represents the optimum thermodynamic working conditions for a given area of the heat exchangers.  2001 Éditions scientifiques et médicales Elsevier SAS</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/6182642" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="93ae9c383501696132de93507063eb0e" rel="nofollow" data-download="{"attachment_id":48979998,"asset_id":6182642,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/48979998/download_file?st=MTczOTgxNzcyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="9431010" href="https://unifi.academia.edu/RinaldoRinaldi">Rinaldo Rinaldi</a><script data-card-contents-for-user="9431010" type="text/json">{"id":9431010,"first_name":"Rinaldo","last_name":"Rinaldi","domain_name":"unifi","page_name":"RinaldoRinaldi","display_name":"Rinaldo Rinaldi","profile_url":"https://unifi.academia.edu/RinaldoRinaldi?f_ri=187812","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_6182642 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="6182642"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 6182642, container: ".js-paper-rank-work_6182642", });

Yet, the refrigerators commonly used for this purpose have improvable efficiency levels. Their performance, as shown by the literature, is highly influenced by the size of the heat exchangers and by internal irreversibilities. In this paper the maximum coefficient of performance (COP) is obtained for an irreversible inverse Rankine cycle refrigerator working with the environmentally friendly fluid R134a. This is a steady-state refrigerator working as an open system which consumes external work, subtracts heat from a cold fluid stream at an inlet fixed temperature and assigns it to a higher fixed inlet temperature stream. Heat transfer irreversibilities in the shell-and-tube heat exchangers and external friction losses in the water streams are considered, ignoring only the internal pressure drop of vapor. A simulation program was developed to search the maximum COP at given external fluid temperatures, as a function of mass flows, dimensions and temperature differences in the heat exchangers. Owing to the large number of control variables involved, a numerical optimisation method was used to determine the maximum COP. The proposed method is fast, producing the maximum with acceptable approximation. It provides the refrigerating fluid evaporating and condensing pressures, the heat exchanger dimensions, and the water flow rates for a given cooling power with predefined inlet temperatures of cold and hot water streams. The heat exchanger area closely conditions the COP, so each maximum represents the optimum thermodynamic working conditions for a given area of the heat exchangers.  2001 Éditions scientifiques et médicales Elsevier SAS","downloadable_attachments":[{"id":48979998,"asset_id":6182642,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":9431010,"first_name":"Rinaldo","last_name":"Rinaldi","domain_name":"unifi","page_name":"RinaldoRinaldi","display_name":"Rinaldo Rinaldi","profile_url":"https://unifi.academia.edu/RinaldoRinaldi?f_ri=187812","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=187812","nofollow":true},{"id":305,"name":"Applied Mathematics","url":"https://www.academia.edu/Documents/in/Applied_Mathematics?f_ri=187812","nofollow":true},{"id":522,"name":"Thermodynamics","url":"https://www.academia.edu/Documents/in/Thermodynamics?f_ri=187812","nofollow":true},{"id":6177,"name":"Modeling","url":"https://www.academia.edu/Documents/in/Modeling?f_ri=187812","nofollow":true},{"id":8067,"name":"Heat Transfer","url":"https://www.academia.edu/Documents/in/Heat_Transfer?f_ri=187812"},{"id":19517,"name":"Heat Exchanger","url":"https://www.academia.edu/Documents/in/Heat_Exchanger?f_ri=187812"},{"id":31913,"name":"Solar Absorption Cycle Refrigeration","url":"https://www.academia.edu/Documents/in/Solar_Absorption_Cycle_Refrigeration?f_ri=187812"},{"id":187812,"name":"Thermal Sciences","url":"https://www.academia.edu/Documents/in/Thermal_Sciences?f_ri=187812"},{"id":209555,"name":"Open Systems","url":"https://www.academia.edu/Documents/in/Open_Systems?f_ri=187812"},{"id":234860,"name":"Steady state","url":"https://www.academia.edu/Documents/in/Steady_state?f_ri=187812"},{"id":251651,"name":"Environmental Impact","url":"https://www.academia.edu/Documents/in/Environmental_Impact?f_ri=187812"},{"id":276845,"name":"Organic rankine cycle","url":"https://www.academia.edu/Documents/in/Organic_rankine_cycle?f_ri=187812"},{"id":331203,"name":"Pressure Drop","url":"https://www.academia.edu/Documents/in/Pressure_Drop?f_ri=187812"},{"id":352331,"name":"Coefficient of Performance","url":"https://www.academia.edu/Documents/in/Coefficient_of_Performance?f_ri=187812"},{"id":406331,"name":"Refrigerator","url":"https://www.academia.edu/Documents/in/Refrigerator?f_ri=187812"},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering?f_ri=187812"},{"id":789521,"name":"Optimal Design","url":"https://www.academia.edu/Documents/in/Optimal_Design?f_ri=187812"},{"id":899389,"name":"Open System","url":"https://www.academia.edu/Documents/in/Open_System?f_ri=187812"},{"id":1793525,"name":"Heat exchanger design","url":"https://www.academia.edu/Documents/in/Heat_exchanger_design?f_ri=187812"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_21075100" data-work_id="21075100" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/21075100/A_numerical_study_of_channel_to_channel_flow_cross_over_through_the_gas_diffusion_layer_in_a_PEM_fuel_cell_flow_system_using_a_serpentine_channel_with_a_trapezoidal_cross_sectional_shape">A numerical study of channel-to-channel flow cross-over through the gas diffusion layer in a PEM-fuel-cell flow system using a serpentine channel with a trapezoidal cross-sectional shape</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">A numerical study of channel-to-channel flow cross-over through the gas diffusion layer in a PEM-fuel-cell flow system using a serpentine channel with a trapezoidal cross-sectional shape ✩ Abstract A numerical study of pressure... <a class="more_link u-tcGrayDark u-linkUnstyled" data-container=".work_21075100" data-show=".complete" data-hide=".summarized" data-more-link-behavior="true" href="#">more</a></div><div class="complete hidden">A numerical study of channel-to-channel flow cross-over through the gas diffusion layer in a PEM-fuel-cell flow system using a serpentine channel with a trapezoidal cross-sectional shape ✩ Abstract A numerical study of pressure distribution and flow cross-over through the gas diffusion layer (GDL) in a PEMFC flow plate using a serpentine channel system has been undertaken for the case where the channel has a trapezoidal cross-sectional shape.

The effects of various cross-stream positions (i.e., y c ¼ 0e1.5) of the circular cylinder on the flow and heat transfer characteristics of the backward-facing step flow has been numerically explored for the Reynolds number range 1e200 and Prandtl number of 0.71 (air). The governing continuity, NaviereStokes and energy equations along with appropriate boundary conditions are solved by using FLUENT. The flow and thermal fields have been explained by streamline and isotherm profiles, respectively; however, no temperature dependency effects are considered for the flow viscosity and thermal conductivity. The engineering parameters like wake/recirculation length, total drag coefficient and average Nusselt number, etc. are calculated for the above range of conditions. The present results show an enhancement in the peak Nusselt value of up to 155% using a circular cylinder as compared to the unobstructed case (i.e., without cylinder). Finally, simple correlations for total drag coefficient and peak Nusselt number are obtained for the above range of conditions.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/73023743" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="7f5fa82e042db5b01094c46d4ac44b6e" rel="nofollow" data-download="{"attachment_id":81710631,"asset_id":73023743,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/81710631/download_file?st=MTczOTgxNzcyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="183634491" href="https://independent.academia.edu/AnkitKumar2584">Ankit Kumar</a><script data-card-contents-for-user="183634491" type="text/json">{"id":183634491,"first_name":"Ankit","last_name":"Kumar","domain_name":"independent","page_name":"AnkitKumar2584","display_name":"Ankit Kumar","profile_url":"https://independent.academia.edu/AnkitKumar2584?f_ri=187812","photo":"https://0.academia-photos.com/183634491/80873672/69458768/s65_ankit.kumar.jpeg"}</script></span></span></li><li class="js-paper-rank-work_73023743 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="73023743"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 73023743, container: ".js-paper-rank-work_73023743", });

The effects of various cross-stream positions (i.e., y c ¼ 0e1.5) of the circular cylinder on the flow and heat transfer characteristics of the backward-facing step flow has been numerically explored for the Reynolds number range 1e200 and Prandtl number of 0.71 (air). The governing continuity, NaviereStokes and energy equations along with appropriate boundary conditions are solved by using FLUENT. The flow and thermal fields have been explained by streamline and isotherm profiles, respectively; however, no temperature dependency effects are considered for the flow viscosity and thermal conductivity. The engineering parameters like wake/recirculation length, total drag coefficient and average Nusselt number, etc. are calculated for the above range of conditions. The present results show an enhancement in the peak Nusselt value of up to 155% using a circular cylinder as compared to the unobstructed case (i.e., without cylinder). Finally, simple correlations for total drag coefficient and peak Nusselt number are obtained for the above range of conditions.","downloadable_attachments":[{"id":81710631,"asset_id":73023743,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":183634491,"first_name":"Ankit","last_name":"Kumar","domain_name":"independent","page_name":"AnkitKumar2584","display_name":"Ankit Kumar","profile_url":"https://independent.academia.edu/AnkitKumar2584?f_ri=187812","photo":"https://0.academia-photos.com/183634491/80873672/69458768/s65_ankit.kumar.jpeg"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=187812","nofollow":true},{"id":305,"name":"Applied Mathematics","url":"https://www.academia.edu/Documents/in/Applied_Mathematics?f_ri=187812","nofollow":true},{"id":8067,"name":"Heat Transfer","url":"https://www.academia.edu/Documents/in/Heat_Transfer?f_ri=187812","nofollow":true},{"id":176527,"name":"Laminar Flow","url":"https://www.academia.edu/Documents/in/Laminar_Flow?f_ri=187812","nofollow":true},{"id":187812,"name":"Thermal Sciences","url":"https://www.academia.edu/Documents/in/Thermal_Sciences?f_ri=187812"},{"id":225293,"name":"Navier Stokes","url":"https://www.academia.edu/Documents/in/Navier_Stokes?f_ri=187812"},{"id":246758,"name":"Thermal Conductivity","url":"https://www.academia.edu/Documents/in/Thermal_Conductivity?f_ri=187812"},{"id":247487,"name":"Temperature Dependence","url":"https://www.academia.edu/Documents/in/Temperature_Dependence?f_ri=187812"},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering?f_ri=187812"},{"id":685328,"name":"Drag Coefficient","url":"https://www.academia.edu/Documents/in/Drag_Coefficient?f_ri=187812"},{"id":698667,"name":"Nusselt Number","url":"https://www.academia.edu/Documents/in/Nusselt_Number?f_ri=187812"},{"id":867022,"name":"Boundary Condition","url":"https://www.academia.edu/Documents/in/Boundary_Condition?f_ri=187812"},{"id":871120,"name":"Circular Cylinder","url":"https://www.academia.edu/Documents/in/Circular_Cylinder?f_ri=187812"},{"id":890685,"name":"Forced Convection","url":"https://www.academia.edu/Documents/in/Forced_Convection?f_ri=187812"},{"id":1008960,"name":"Reynolds Number","url":"https://www.academia.edu/Documents/in/Reynolds_Number?f_ri=187812"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_5732651" data-work_id="5732651" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/5732651/Investigation_of_a_wire_plate_micro_heat_pipe_array">Investigation of a wire plate micro heat pipe array</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">In the present work, experimental and theoretical investigations have been conducted on a copper/water wire plate micro heat pipe (MHP).

Their major advantages as compared to heat pipes are an ability to operate against gravity and a greater maximum heat transport capability. In this paper, a literature review is carried out in order to investigate how various parameters affect the LHP operational characteristics. This review is based on the most recent published experimental and theoretical studies. After a reminder of the LHP operating principle and thermodynamic cycle, their operating limits are described. The LHP thermal resistance and maximum heat transfer capability are affected by the choice of the working fluid, the fill charge ratio, the porous wick geometry and thermal properties, the sink and ambient temperature levels, the design of the evaporator and compensation chamber, the elevation and tilt, the presence of non-condensable gases, the pressure drops of the fluid along the loop. The overall objective for this paper is to point the state-of-the-art for the related technology for future design and applications, where the constraints related to the LHPs are detailed and discussed.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/15907338" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="c3d3f21f9e03aa7421b31d02ce902af2" rel="nofollow" data-download="{"attachment_id":42831137,"asset_id":15907338,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/42831137/download_file?st=MTczOTgxNzcyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="35067210" href="https://independent.academia.edu/JocelynBonjour">Jocelyn Bonjour</a><script data-card-contents-for-user="35067210" type="text/json">{"id":35067210,"first_name":"Jocelyn","last_name":"Bonjour","domain_name":"independent","page_name":"JocelynBonjour","display_name":"Jocelyn Bonjour","profile_url":"https://independent.academia.edu/JocelynBonjour?f_ri=187812","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_15907338 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="15907338"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 15907338, container: ".js-paper-rank-work_15907338", });

In addition, the Nusselt number and the average Nusselt number, both based on the heated plate height, are presented in graphical form. At the end, optimal channel configurations expressed in terms of the highest average Nusselt number are obtained for the pair of pre-assigned Grashof numbers.","downloadable_attachments":[{"id":48635433,"asset_id":7007627,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":11923895,"first_name":"Oronzio","last_name":"Manca","domain_name":"unina2","page_name":"OManca","display_name":"Oronzio Manca","profile_url":"https://unina2.academia.edu/OManca?f_ri=187812","photo":"https://0.academia-photos.com/11923895/4150093/4835118/s65_oronzio.manca.jpg"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=187812","nofollow":true},{"id":305,"name":"Applied Mathematics","url":"https://www.academia.edu/Documents/in/Applied_Mathematics?f_ri=187812","nofollow":true},{"id":8067,"name":"Heat Transfer","url":"https://www.academia.edu/Documents/in/Heat_Transfer?f_ri=187812","nofollow":true},{"id":12022,"name":"Numerical Analysis","url":"https://www.academia.edu/Documents/in/Numerical_Analysis?f_ri=187812","nofollow":true},{"id":100257,"name":"Natural Convection","url":"https://www.academia.edu/Documents/in/Natural_Convection?f_ri=187812"},{"id":152690,"name":"Boundary Conditions","url":"https://www.academia.edu/Documents/in/Boundary_Conditions?f_ri=187812"},{"id":187812,"name":"Thermal Sciences","url":"https://www.academia.edu/Documents/in/Thermal_Sciences?f_ri=187812"},{"id":201306,"name":"Heat Flux","url":"https://www.academia.edu/Documents/in/Heat_Flux?f_ri=187812"},{"id":220108,"name":"Heat Exchangers","url":"https://www.academia.edu/Documents/in/Heat_Exchangers?f_ri=187812"},{"id":225293,"name":"Navier Stokes","url":"https://www.academia.edu/Documents/in/Navier_Stokes?f_ri=187812"},{"id":332277,"name":"Finite Volume","url":"https://www.academia.edu/Documents/in/Finite_Volume?f_ri=187812"},{"id":465327,"name":"Finite Temperature Field Theory","url":"https://www.academia.edu/Documents/in/Finite_Temperature_Field_Theory?f_ri=187812"},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering?f_ri=187812"},{"id":698667,"name":"Nusselt Number","url":"https://www.academia.edu/Documents/in/Nusselt_Number?f_ri=187812"},{"id":898062,"name":"Flow Rate","url":"https://www.academia.edu/Documents/in/Flow_Rate?f_ri=187812"},{"id":2430296,"name":"Proof of Concept","url":"https://www.academia.edu/Documents/in/Proof_of_Concept?f_ri=187812"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_68116889" data-work_id="68116889" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/68116889/A_parametric_study_of_phase_change_material_PCM_based_heat_sinks">A parametric study of phase change material (PCM)-based heat sinks</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">A numerical study is conducted to evaluate the thermal characteristics of a PCM-based heat sink which can be potentially used for cooling of mobile electronic devices such as personal digital assistants (PDAs) and notebooks.

These phenomena are principally linked to the continuous movement of the electric arc root on the anode wall in the plasma gun.

This paper presents an attempt to develop a time-dependent and 3-D model of the plasma spray process that can provide a useful insight in the time-evolution of the performance of the process. The effect of the transient behaviour of the arc on the gas flow is modelled with a time dependant heat source located inside the nozzle and evolving with the arc voltage.

The second dealt the time-dependant simulation of the flow.","downloadable_attachments":[{"id":50161304,"asset_id":3721593,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":4555550,"first_name":"Armelle","last_name":"Vardelle","domain_name":"independent","page_name":"ArmelleVardelle","display_name":"Armelle Vardelle","profile_url":"https://independent.academia.edu/ArmelleVardelle?f_ri=187812","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=187812","nofollow":true},{"id":305,"name":"Applied Mathematics","url":"https://www.academia.edu/Documents/in/Applied_Mathematics?f_ri=187812","nofollow":true},{"id":62455,"name":"Plasma spray coatings","url":"https://www.academia.edu/Documents/in/Plasma_spray_coatings?f_ri=187812","nofollow":true},{"id":72413,"name":"Flow","url":"https://www.academia.edu/Documents/in/Flow?f_ri=187812","nofollow":true},{"id":94065,"name":"Arc","url":"https://www.academia.edu/Documents/in/Arc?f_ri=187812"},{"id":187812,"name":"Thermal Sciences","url":"https://www.academia.edu/Documents/in/Thermal_Sciences?f_ri=187812"},{"id":234860,"name":"Steady state","url":"https://www.academia.edu/Documents/in/Steady_state?f_ri=187812"},{"id":394477,"name":"Time Dependent","url":"https://www.academia.edu/Documents/in/Time_Dependent?f_ri=187812"},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering?f_ri=187812"},{"id":897122,"name":"Gas Flow","url":"https://www.academia.edu/Documents/in/Gas_Flow?f_ri=187812"},{"id":1120502,"name":"Experimental Data","url":"https://www.academia.edu/Documents/in/Experimental_Data?f_ri=187812"},{"id":1258584,"name":"Plasma Spraying","url":"https://www.academia.edu/Documents/in/Plasma_Spraying?f_ri=187812"},{"id":1698479,"name":"Particle Deposition","url":"https://www.academia.edu/Documents/in/Particle_Deposition?f_ri=187812"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_67853868" data-work_id="67853868" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" rel="nofollow" href="https://www.academia.edu/67853868/Forced_convection_in_non_circular_tubes_with_non_linear_viscoelastic_fluids_including_viscous_dissipation">Forced convection in non-circular tubes with non-linear viscoelastic fluids including viscous dissipation</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Abstract The steady, laminar, non-isothermal fully developed flow of a class of non-linear viscoelastic fluids in tubes of arbitrary contour is analyzed under constant wall heat flux including viscous dissipation.

The system has been considered as a conjugate problem with interaction of the wall with loop fluid, cooling stream and ambient along different sections of the loop. Non-dimensional form of coupled conservation equations have been solved using 1-d numerical techniques. Predicted values exhibited good degree of agreement with corresponding experimental data from the literature. As NCL is a self-sustaining system and it is difficult to control any flow-related parameters from outside once the system is under operation, it is very much essential to analyze the role of different geometric parameters at design level itself. Detailed parametric variation has been attempted to find operating limits of geometric parameters. Consideration of heat loss to ambient from the loop wall has been found to have significant effect on suitability of system dimensions, particularly under cooler atmospheric conditions. A loop with shorter height and smaller diameter yields higher effectiveness, i.e., transfers larger proportion of input energy to the sink, but employing lower circulation rate due to reduced buoyancy. Longer heating section yields enhanced heat transfer from wall to fluid and has a stabilizing effect on the system. Wall materials with higher thermal conductivity have been found to be more effective to avoid large thermal gradients within the system.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/15094435" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="3a03eb560f298bcca970285abe2c702a" rel="nofollow" data-download="{"attachment_id":43588717,"asset_id":15094435,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/43588717/download_file?st=MTczOTgxNzcyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="2095008" href="https://iitg-in.academia.edu/DipankarBasu">Dipankar Basu</a><script data-card-contents-for-user="2095008" type="text/json">{"id":2095008,"first_name":"Dipankar","last_name":"Basu","domain_name":"iitg-in","page_name":"DipankarBasu","display_name":"Dipankar Basu","profile_url":"https://iitg-in.academia.edu/DipankarBasu?f_ri=187812","photo":"https://0.academia-photos.com/2095008/683150/847772/s65_dipankar.basu.jpg"}</script></span></span></li><li class="js-paper-rank-work_15094435 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="15094435"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 15094435, container: ".js-paper-rank-work_15094435", });

Wall materials with higher thermal conductivity have been found to be more effective to avoid large thermal gradients within the system.","downloadable_attachments":[{"id":43588717,"asset_id":15094435,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":2095008,"first_name":"Dipankar","last_name":"Basu","domain_name":"iitg-in","page_name":"DipankarBasu","display_name":"Dipankar Basu","profile_url":"https://iitg-in.academia.edu/DipankarBasu?f_ri=187812","photo":"https://0.academia-photos.com/2095008/683150/847772/s65_dipankar.basu.jpg"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=187812","nofollow":true},{"id":305,"name":"Applied Mathematics","url":"https://www.academia.edu/Documents/in/Applied_Mathematics?f_ri=187812","nofollow":true},{"id":174347,"name":"Thermal","url":"https://www.academia.edu/Documents/in/Thermal?f_ri=187812","nofollow":true},{"id":187812,"name":"Thermal Sciences","url":"https://www.academia.edu/Documents/in/Thermal_Sciences?f_ri=187812","nofollow":true},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering?f_ri=187812"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_5383561" data-work_id="5383561" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/5383561/A_dynamic_model_of_a_shell_and_tube_condenser_operating_in_a_vapour_compression_refrigeration_plant">A dynamic model of a shell-and-tube condenser operating in a vapour compression refrigeration plant</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">This work presents a mathematical model of a shell-and-tube condenser based on mass continuity, energy conservation and heat transfer physical fundamentals, whose methodology can be easily adapted for modelling any type of condenser.

with relative rotation of the inner and outer cylinders. Two different types of boundary conditions are considered: at the first case both cylinders are isothermal and kept at different temperatures and in the second case the heat flux is kept constant at the outer cylinder and the inner one is isothermal. Analytical expressions for dimensionless temperature profile (Θ), dimensionless entropy generation number (N S ), and the Bejan number (Be) are obtained. The effect of velocity ratio (β), the group parameter (Br/Ω), the Brinkman number (Br), and fluid elasticity (ε We 2 ) on the above parameters are investigated.

Two different types of boundary conditions are considered: at the first case both cylinders are isothermal and kept at different temperatures and in the second case the heat flux is kept constant at the outer cylinder and the inner one is isothermal. Analytical expressions for dimensionless temperature profile (Θ), dimensionless entropy generation number (N S ), and the Bejan number (Be) are obtained. The effect of velocity ratio (β), the group parameter (Br/Ω), the Brinkman number (Br), and fluid elasticity (ε We 2 ) on the above parameters are investigated. The results show that the total entropy generation number decreases as the fluid elasticity increases. The results also show that entropy generation number increases with increasing Brinkman number.","downloadable_attachments":[{"id":50032053,"asset_id":4099442,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":4946159,"first_name":"fariborz","last_name":"rashidi","domain_name":"google","page_name":"fariborzrashidi","display_name":"fariborz rashidi","profile_url":"https://google.academia.edu/fariborzrashidi?f_ri=187812","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=187812","nofollow":true},{"id":305,"name":"Applied Mathematics","url":"https://www.academia.edu/Documents/in/Applied_Mathematics?f_ri=187812","nofollow":true},{"id":8067,"name":"Heat Transfer","url":"https://www.academia.edu/Documents/in/Heat_Transfer?f_ri=187812","nofollow":true},{"id":149188,"name":"Entropy generation","url":"https://www.academia.edu/Documents/in/Entropy_generation?f_ri=187812","nofollow":true},{"id":187812,"name":"Thermal Sciences","url":"https://www.academia.edu/Documents/in/Thermal_Sciences?f_ri=187812"},{"id":201306,"name":"Heat Flux","url":"https://www.academia.edu/Documents/in/Heat_Flux?f_ri=187812"},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering?f_ri=187812"},{"id":867022,"name":"Boundary Condition","url":"https://www.academia.edu/Documents/in/Boundary_Condition?f_ri=187812"},{"id":890685,"name":"Forced Convection","url":"https://www.academia.edu/Documents/in/Forced_Convection?f_ri=187812"},{"id":1151301,"name":"Annular Flow","url":"https://www.academia.edu/Documents/in/Annular_Flow?f_ri=187812"},{"id":1231330,"name":"Constitutive Equation","url":"https://www.academia.edu/Documents/in/Constitutive_Equation?f_ri=187812"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_6025775" data-work_id="6025775" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/6025775/Thermal_properties_of_knitted_fabrics_made_from_cotton_and_regenerated_bamboo_cellulosic_fibres">Thermal properties of knitted fabrics made from cotton and regenerated bamboo cellulosic fibres</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">This paper presents the thermal properties of different knitted fabric structures made from cotton, regenerated bamboo and cotton-bamboo blended yarns.

The governing continuity, momentum and energy equations for a laminar flow are being discretized using a finite volume approach using a power law profile approximation and has been solved iteratively, through alternate direction implicit, using the SIMPLER algorithm. The thermal conductivity of nanofluid has been determined by model proposed by Patel et al. Study has been conducted considering the fluid as Newtonian as well as non-Newtonian for a wide range of Reynolds number (Re = 5 to 1500) and solid volume fraction (0.00 φ 0.050). It has been observed that the heat transfer augmentation is possible using nanofluid in comparison to conventional fluids for both the cases. The rate of heat transfer increases with the increase in flow as well as increase in solid volume fraction of the nanofluid. Unlike natural convection the increase in heat transfer is almost same for both the cases.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/6940025" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="d80a1f1f4f359b8123fd329d74424c95" rel="nofollow" data-download="{"attachment_id":48659723,"asset_id":6940025,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/48659723/download_file?st=MTczOTgxNzcyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="11719367" href="https://jadavpur.academia.edu/NiladriChakraborty">Niladri Chakraborty</a><script data-card-contents-for-user="11719367" type="text/json">{"id":11719367,"first_name":"Niladri","last_name":"Chakraborty","domain_name":"jadavpur","page_name":"NiladriChakraborty","display_name":"Niladri Chakraborty","profile_url":"https://jadavpur.academia.edu/NiladriChakraborty?f_ri=187812","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_6940025 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="6940025"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 6940025, container: ".js-paper-rank-work_6940025", });

The governing continuity, momentum and energy equations for a laminar flow are being discretized using a finite volume approach using a power law profile approximation and has been solved iteratively, through alternate direction implicit, using the SIMPLER algorithm. The thermal conductivity of nanofluid has been determined by model proposed by Patel et al. Study has been conducted considering the fluid as Newtonian as well as non-Newtonian for a wide range of Reynolds number (Re = 5 to 1500) and solid volume fraction (0.00 φ 0.050). It has been observed that the heat transfer augmentation is possible using nanofluid in comparison to conventional fluids for both the cases. The rate of heat transfer increases with the increase in flow as well as increase in solid volume fraction of the nanofluid. Unlike natural convection the increase in heat transfer is almost same for both the cases.","downloadable_attachments":[{"id":48659723,"asset_id":6940025,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":11719367,"first_name":"Niladri","last_name":"Chakraborty","domain_name":"jadavpur","page_name":"NiladriChakraborty","display_name":"Niladri Chakraborty","profile_url":"https://jadavpur.academia.edu/NiladriChakraborty?f_ri=187812","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=187812","nofollow":true},{"id":305,"name":"Applied Mathematics","url":"https://www.academia.edu/Documents/in/Applied_Mathematics?f_ri=187812","nofollow":true},{"id":8067,"name":"Heat Transfer","url":"https://www.academia.edu/Documents/in/Heat_Transfer?f_ri=187812","nofollow":true},{"id":80692,"name":"Copper","url":"https://www.academia.edu/Documents/in/Copper?f_ri=187812","nofollow":true},{"id":100257,"name":"Natural Convection","url":"https://www.academia.edu/Documents/in/Natural_Convection?f_ri=187812"},{"id":108044,"name":"Non Newtonian","url":"https://www.academia.edu/Documents/in/Non_Newtonian?f_ri=187812"},{"id":113890,"name":"Power Law","url":"https://www.academia.edu/Documents/in/Power_Law?f_ri=187812"},{"id":144723,"name":"Nanofluid","url":"https://www.academia.edu/Documents/in/Nanofluid?f_ri=187812"},{"id":174347,"name":"Thermal","url":"https://www.academia.edu/Documents/in/Thermal?f_ri=187812"},{"id":176527,"name":"Laminar Flow","url":"https://www.academia.edu/Documents/in/Laminar_Flow?f_ri=187812"},{"id":187812,"name":"Thermal Sciences","url":"https://www.academia.edu/Documents/in/Thermal_Sciences?f_ri=187812"},{"id":246758,"name":"Thermal Conductivity","url":"https://www.academia.edu/Documents/in/Thermal_Conductivity?f_ri=187812"},{"id":332277,"name":"Finite Volume","url":"https://www.academia.edu/Documents/in/Finite_Volume?f_ri=187812"},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering?f_ri=187812"},{"id":1008960,"name":"Reynolds Number","url":"https://www.academia.edu/Documents/in/Reynolds_Number?f_ri=187812"},{"id":2295024,"name":"Volume Fraction","url":"https://www.academia.edu/Documents/in/Volume_Fraction?f_ri=187812"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_74378285" data-work_id="74378285" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/74378285/R%C3%A9solution_dun_probl%C3%A8me_inverse_de_convection_diffusion_par_une_m%C3%A9thode_de_perturbation_singuli%C3%A8re">Résolution d'un problème inverse de convection–diffusion par une méthode de perturbation singulière</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">-Le but de ce travail est de résoudre un problème inverse de convection diffusion pour un écoulement de fluide newtonien incompressible entre deux plaques planes lorsque le régime dynamique est atteint.

An ideal periodic isotropic structure of tetrakaidecahedron shape i.e. Kelvin cell is studied. The geometrical parameters of casted metal foams are obtained using iMorph (in-house code). We have proposed an analytical model in order to obtain geometrical parameters correctly as they have substantial influence on thermal and hydraulic phenomena, where strut geometry is of primary importance. Various relationships between different geometrical parameters and porosities are presented. The analytical results are fully compared with the experimental data in the literature and measured morphological data. The relationship of geometrical parameters with physical properties such as effective thermal conductivity is equally important. The range of solid to fluid phase conductivity ratios (l s /l f ) studied is from 10 to 30,000 and for different porosities (80e95%). A modified correlation term, F is introduced in order to take account of thermal conductivities of constituent phases using electrical resistor model. An excellent agreement has been observed between the predicted correlation and experimental data.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/29586802" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="47060223b9e1b085eb5a64894e2ae70e" rel="nofollow" data-download="{"attachment_id":50029802,"asset_id":29586802,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/50029802/download_file?st=MTczOTgxNzcyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="55945289" href="https://otmed.academia.edu/FredericTopin">Frederic Topin</a><script data-card-contents-for-user="55945289" type="text/json">{"id":55945289,"first_name":"Frederic","last_name":"Topin","domain_name":"otmed","page_name":"FredericTopin","display_name":"Frederic Topin","profile_url":"https://otmed.academia.edu/FredericTopin?f_ri=187812","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_29586802 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="29586802"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 29586802, container: ".js-paper-rank-work_29586802", });

An ideal periodic isotropic structure of tetrakaidecahedron shape i.e. Kelvin cell is studied. The geometrical parameters of casted metal foams are obtained using iMorph (in-house code). We have proposed an analytical model in order to obtain geometrical parameters correctly as they have substantial influence on thermal and hydraulic phenomena, where strut geometry is of primary importance. Various relationships between different geometrical parameters and porosities are presented. The analytical results are fully compared with the experimental data in the literature and measured morphological data. The relationship of geometrical parameters with physical properties such as effective thermal conductivity is equally important. The range of solid to fluid phase conductivity ratios (l s /l f ) studied is from 10 to 30,000 and for different porosities (80e95%). A modified correlation term, F is introduced in order to take account of thermal conductivities of constituent phases using electrical resistor model. An excellent agreement has been observed between the predicted correlation and experimental data.","downloadable_attachments":[{"id":50029802,"asset_id":29586802,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":55945289,"first_name":"Frederic","last_name":"Topin","domain_name":"otmed","page_name":"FredericTopin","display_name":"Frederic Topin","profile_url":"https://otmed.academia.edu/FredericTopin?f_ri=187812","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=187812","nofollow":true},{"id":305,"name":"Applied Mathematics","url":"https://www.academia.edu/Documents/in/Applied_Mathematics?f_ri=187812","nofollow":true},{"id":187812,"name":"Thermal Sciences","url":"https://www.academia.edu/Documents/in/Thermal_Sciences?f_ri=187812","nofollow":true},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering?f_ri=187812","nofollow":true}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_22497313" data-work_id="22497313" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/22497313/Investigations_of_thermal_conductivity_and_viscosity_of_nanofluids">Investigations of thermal conductivity and viscosity of nanofluids</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">A combined experimental and theoretical study on the effective thermal conductivity and viscosity of nanofluids is conducted.

The study is restricted to laminar flow conditions. In order to identify the relevant non-dimensional groups that define the transient natural convection phenomenon that occurs, a non-dimensional analysis is carried out. The long-term behaviour of the fluid is modeled by formulating a prediction model based on global balances. A parametric study by means of several multidimensional numerical simulations led to correlate the Nusselt number and the transient mean fluid temperature, to feed the global model proposed.

The most relevant particularities of the numerical model developed are also pointed out.","downloadable_attachments":[{"id":39170803,"asset_id":16764809,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":18961510,"first_name":"Ivette","last_name":"Rodríguez","domain_name":"upc","page_name":"IvetteRodríguez","display_name":"Ivette Rodríguez","profile_url":"https://upc.academia.edu/IvetteRodr%C3%ADguez?f_ri=187812","photo":"https://0.academia-photos.com/18961510/5266283/6021444/s65_ivette.rodr_guez.jpg"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=187812","nofollow":true},{"id":305,"name":"Applied Mathematics","url":"https://www.academia.edu/Documents/in/Applied_Mathematics?f_ri=187812","nofollow":true},{"id":59579,"name":"Dimensional Analysis","url":"https://www.academia.edu/Documents/in/Dimensional_Analysis?f_ri=187812","nofollow":true},{"id":60658,"name":"Numerical Simulation","url":"https://www.academia.edu/Documents/in/Numerical_Simulation?f_ri=187812","nofollow":true},{"id":100257,"name":"Natural Convection","url":"https://www.academia.edu/Documents/in/Natural_Convection?f_ri=187812"},{"id":176527,"name":"Laminar Flow","url":"https://www.academia.edu/Documents/in/Laminar_Flow?f_ri=187812"},{"id":187812,"name":"Thermal Sciences","url":"https://www.academia.edu/Documents/in/Thermal_Sciences?f_ri=187812"},{"id":224767,"name":"Prediction Model","url":"https://www.academia.edu/Documents/in/Prediction_Model?f_ri=187812"},{"id":497452,"name":"Numerical Model","url":"https://www.academia.edu/Documents/in/Numerical_Model?f_ri=187812"},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering?f_ri=187812"},{"id":698667,"name":"Nusselt Number","url":"https://www.academia.edu/Documents/in/Nusselt_Number?f_ri=187812"},{"id":848110,"name":"CFD simulation","url":"https://www.academia.edu/Documents/in/CFD_simulation?f_ri=187812"},{"id":896204,"name":"Numerical Solution","url":"https://www.academia.edu/Documents/in/Numerical_Solution?f_ri=187812"},{"id":2003399,"name":"Parametric Study","url":"https://www.academia.edu/Documents/in/Parametric_Study?f_ri=187812"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_5017251" data-work_id="5017251" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/5017251/Numerical_study_of_turbulent_flow_and_heat_transfer_characteristics_of_nanofluids_considering_variable_properties">Numerical study of turbulent flow and heat transfer characteristics of nanofluids considering variable properties</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Turbulent flow and heat transfer of three different nanofluids (CuO, Al 2 O 3 and SiO 2 ) in an ethylene glycol and water mixture flowing through a circular tube under constant heat flux condition have been numerically analyzed.

Experimental tests were conducted on a reduced-scale electric submersible pump motor. In addition, theoretical simulations were performed using a finite-element based software package for a reduced-scale electric submersible pump motor, and a full-scale electric submersible pump motor and its power cable of flat and round types. Compared to the cases of running the motor under balanced or unbalanced conditions, the single-phasing operation of eccentric wells gives the highest localized magnetic-flux and eddy current densities, hence the possibility of localized corrosion increases.

The problem involves a fluid flowing inside a horizontal finned tube surrounded by a phase-change material (PCM). The objective of this paper is to predict the temperature distribution, the phase front distribution along the tube and to analyze the effect of fin density and size on the dynamic performance of the system. The problem is modeled as axisymmetric and two-dimensional, and a control volume computer code has been developed for the solution of the corresponding mathematical model. In the experimental arrangement of the tube configuration, two different fin diameters; D fn = 2.7 and 3.2 are considered and the fin density at each fin diameter is varied in the range of N fn = 14-31 fins·m −1 . For a particular geometry then the heat transfer fluid inlet temperature assumes values between −10 • C and −20 • C, and the flow Peclet number is varied in the range from 14 350 to 200 900 accordingly. Comparison between the numerical predictions and the experimental data shows good agreement, even though some effects that are produced by heat transfer to the environment especially at high flow rates neglected in the model but unavoidable in the experiments. Finally, time-wise variation of energy stored by the system is evaluated through instant images of solidification fronts and the combined effect of fin parameters and the flow rate on energy storage is discussed.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/23954392" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="4f8619685dca18def371a3b172e239f0" rel="nofollow" data-download="{"attachment_id":44339514,"asset_id":23954392,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/44339514/download_file?st=MTczOTgxNzcyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="14286249" href="https://independent.academia.edu/MehmetAcar5">Mehmet Acar</a><script data-card-contents-for-user="14286249" type="text/json">{"id":14286249,"first_name":"Mehmet","last_name":"Acar","domain_name":"independent","page_name":"MehmetAcar5","display_name":"Mehmet Acar","profile_url":"https://independent.academia.edu/MehmetAcar5?f_ri=187812","photo":"https://0.academia-photos.com/14286249/5907441/6707813/s65_mehmet.acar.jpg_oh_b1c69bc8f2cd3744d4d67f10aa46e29a_oe_54dda2df___gda___1423928755_95e8d32c0f381d3f9c2cd1bad9d669a1"}</script></span></span></li><li class="js-paper-rank-work_23954392 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="23954392"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 23954392, container: ".js-paper-rank-work_23954392", });

The problem involves a fluid flowing inside a horizontal finned tube surrounded by a phase-change material (PCM). The objective of this paper is to predict the temperature distribution, the phase front distribution along the tube and to analyze the effect of fin density and size on the dynamic performance of the system. The problem is modeled as axisymmetric and two-dimensional, and a control volume computer code has been developed for the solution of the corresponding mathematical model. In the experimental arrangement of the tube configuration, two different fin diameters; D fn = 2.7 and 3.2 are considered and the fin density at each fin diameter is varied in the range of N fn = 14-31 fins·m −1 . For a particular geometry then the heat transfer fluid inlet temperature assumes values between −10 • C and −20 • C, and the flow Peclet number is varied in the range from 14 350 to 200 900 accordingly. Comparison between the numerical predictions and the experimental data shows good agreement, even though some effects that are produced by heat transfer to the environment especially at high flow rates neglected in the model but unavoidable in the experiments. Finally, time-wise variation of energy stored by the system is evaluated through instant images of solidification fronts and the combined effect of fin parameters and the flow rate on energy storage is discussed.","downloadable_attachments":[{"id":44339514,"asset_id":23954392,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":14286249,"first_name":"Mehmet","last_name":"Acar","domain_name":"independent","page_name":"MehmetAcar5","display_name":"Mehmet Acar","profile_url":"https://independent.academia.edu/MehmetAcar5?f_ri=187812","photo":"https://0.academia-photos.com/14286249/5907441/6707813/s65_mehmet.acar.jpg_oh_b1c69bc8f2cd3744d4d67f10aa46e29a_oe_54dda2df___gda___1423928755_95e8d32c0f381d3f9c2cd1bad9d669a1"}],"research_interests":[{"id":60,"name":"Mechanical Engineering","url":"https://www.academia.edu/Documents/in/Mechanical_Engineering?f_ri=187812","nofollow":true},{"id":305,"name":"Applied Mathematics","url":"https://www.academia.edu/Documents/in/Applied_Mathematics?f_ri=187812","nofollow":true},{"id":8067,"name":"Heat Transfer","url":"https://www.academia.edu/Documents/in/Heat_Transfer?f_ri=187812","nofollow":true},{"id":19517,"name":"Heat Exchanger","url":"https://www.academia.edu/Documents/in/Heat_Exchanger?f_ri=187812","nofollow":true},{"id":187673,"name":"Phase Change","url":"https://www.academia.edu/Documents/in/Phase_Change?f_ri=187812"},{"id":187812,"name":"Thermal Sciences","url":"https://www.academia.edu/Documents/in/Thermal_Sciences?f_ri=187812"},{"id":206381,"name":"Phase Change Material","url":"https://www.academia.edu/Documents/in/Phase_Change_Material?f_ri=187812"},{"id":215076,"name":"Fluid flow","url":"https://www.academia.edu/Documents/in/Fluid_flow?f_ri=187812"},{"id":235663,"name":"Temperature Distribution","url":"https://www.academia.edu/Documents/in/Temperature_Distribution?f_ri=187812"},{"id":250447,"name":"Energy Storage","url":"https://www.academia.edu/Documents/in/Energy_Storage?f_ri=187812"},{"id":270366,"name":"Heat Conduction","url":"https://www.academia.edu/Documents/in/Heat_Conduction?f_ri=187812"},{"id":281300,"name":"Thermal Energy Storage","url":"https://www.academia.edu/Documents/in/Thermal_Energy_Storage?f_ri=187812"},{"id":291387,"name":"Mathematical Model","url":"https://www.academia.edu/Documents/in/Mathematical_Model?f_ri=187812"},{"id":332277,"name":"Finite Volume","url":"https://www.academia.edu/Documents/in/Finite_Volume?f_ri=187812"},{"id":554780,"name":"Interdisciplinary Engineering","url":"https://www.academia.edu/Documents/in/Interdisciplinary_Engineering?f_ri=187812"},{"id":898062,"name":"Flow Rate","url":"https://www.academia.edu/Documents/in/Flow_Rate?f_ri=187812"},{"id":898070,"name":"Experimental Measurement","url":"https://www.academia.edu/Documents/in/Experimental_Measurement?f_ri=187812"},{"id":1120502,"name":"Experimental Data","url":"https://www.academia.edu/Documents/in/Experimental_Data?f_ri=187812"},{"id":1143850,"name":"Heat Transfer Fluid Mechanics CFD","url":"https://www.academia.edu/Documents/in/Heat_Transfer_Fluid_Mechanics_CFD?f_ri=187812"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_30121751" data-work_id="30121751" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/30121751/Characterization_of_the_effect_of_surface_roughness_and_texture_on_fluid_flow_past_present_and_future">Characterization of the effect of surface roughness and texture on fluid flow—past, present, and future</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Surface roughness (texture) has an effect on fluid flow in networks which has been studied for well over a century.

The exact effect roughness has on fluid flow has not been completely understood, but a working estimate has been offered by a variety of authors over time. The work of Colebrook, Nikuradse, and Moody has provided practitioners with a method to include at least a first order estimate of roughness effects, but their work has been limited to relative roughness (roughness height to diameter) values of 5% or less. Modern fluidic systems at the mini-and micro-levels routinely violate the 5% relative roughness threshold due to the inability to control the roughness of surfaces to sufficient levels with respect to decreasing system scale. Current work by Kandlikar et al., has extended the traditional methods of assessing surface roughness effects up to 14% relative roughness by including the effect of constricted flow diameters (modified flow diameter based on constrictions caused by surface roughness) and modifying the Moody diagram to reflect new experimental data. The future of micro fluidics would suggest that trends for miniaturization will continue and that further understanding and experimentation will be warranted.

Air was considered as the working fluid. The heated cylinder surface was maintained at a constant heat flux. In this work, circular, square and rectangular nozzles of equal hydraulic diameters were selected for a comparative study. The Reynolds number, Re hyd defined based on the hydraulic diameter of the nozzle was varied from 10,000 to 25,000. The ratio of hydraulic diameter of the nozzle to the diameter of heated cylinder, d hyd /D was maintained at 0.2 for the parametric study. The non-dimensional distance between the nozzle exit and the cylinder, h/d hyd was varied from 4 to 16. For a fixed jet Reynolds number, the mass flow rates through different nozzles are different. Hence, a parametric study was also carried out to know the effect of nozzle shape for various fixed mass flow rates. For this, a modified Reynolds number Re hyd was kept constant for all nozzle shapes. For a fixed jet Reynolds number, heat transfer from the cylinder was higher for the case of rectangular nozzle. On the other hand, for a fixed modified Reynolds number Re hyd , heat transfer rate from the cylinder was found to be higher when the circular nozzle was used. For the same geometry, numerical simulations were also carried out using three different two-equation turbulence models.

This is the first paper on stretching sheet in nanofluids. The model used for the nanofluid incorporates the effects of Brownian motion and thermophoresis.

Energy and exergy models were used for the study. The effects of the hydrodynamic and thermodynamic conditions such as the inlet air temperature, the fluidization velocity and the initial moisture content on the energy efficiency and the exergy efficiency were analyzed. The analysis was carried out using two different materials, wheat and corn. It was observed that the thermodynamic efficiency of the fluidized bed dryer was the lowest at the end of the drying process in conjunction with the moisture removal rate. The inlet air temperature has a strong effect on thermodynamic efficiency for wheat, but for corn, where the diffusion coefficient depends on the temperature and the moisture content of particles, an increase in the drying air temperature did not result in an increase of the efficiency. Furthermore, the energy and exergy efficiencies showed higher values for particles with high initial moisture content while the effect of gas velocity varied depending on the particles. A good agreement was achieved between the model predictions and the available experimental results.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/8635741" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="0acac7b77c472c1634d7d63a0e350685" rel="nofollow" data-download="{"attachment_id":48035222,"asset_id":8635741,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/48035222/download_file?st=MTczOTgxNzcyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="17951994" href="https://independent.academia.edu/syahrulsyahrul2">syahrul syahrul</a><script data-card-contents-for-user="17951994" type="text/json">{"id":17951994,"first_name":"syahrul","last_name":"syahrul","domain_name":"independent","page_name":"syahrulsyahrul2","display_name":"syahrul syahrul","profile_url":"https://independent.academia.edu/syahrulsyahrul2?f_ri=187812","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_8635741 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="8635741"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 8635741, container: ".js-paper-rank-work_8635741", });

The atomization of a hollow cone fuel spray generated by a high pressure swirl injector is studied by means of a numerical technique. The model distinguishes between primary atomization and secondary breakup. The latter was modeled, as done in a previous work on Diesel atomization, using different mechanisms as the droplet Weber number changes. At first the spray atomization in a quiescent chamber, at ambient pressure and temperature, was considered. The validation of the model was made comparing the numerical penetration and spray morphology with experimental results. Combustion simulations were also performed comparing numerical results with experimental data of a GDI (Gasoline Direct Injection), 4 stroke, 4 cylinder, 4 valves per cylinder engine.

The atomization of a hollow cone fuel spray generated by a high pressure swirl injector is studied by means of a numerical technique. The model distinguishes between primary atomization and secondary breakup. The latter was modeled, as done in a previous work on Diesel atomization, using different mechanisms as the droplet Weber number changes. At first the spray atomization in a quiescent chamber, at ambient pressure and temperature, was considered. The validation of the model was made comparing the numerical penetration and spray morphology with experimental results. Combustion simulations were also performed comparing numerical results with experimental data of a GDI (Gasoline Direct Injection), 4 stroke, 4 cylinder, 4 valves per cylinder engine. Such simulations were made to analyze and understand the mixture formation mechanism in both stoichiometric and stratified operation mode. The results show how, the interaction between the air motion and the fuel spray, leading factor in spray atomization, is fundamental to realize an efficient mixture formation and combustion locally very lean, typical of stratified charge combustion.  2005 Elsevier SAS.

A two component non-homogenous equilibrium model is used for the nanofluid that incorporates the effects of Brownian motion and thermophoresis. Variable thermal conductivity and variable viscosity are taken into account in this work. Finite volume method is used to solve governing equations. Results are presented by streamlines, isotherms, nanoparticle distribution, local and mean Nusselt numbers and nanoparticle profiles at top and bottom side. Comparison of two cases as absence of Brownian and thermophoresis effects and presence of Brownian and thermophoresis effects showed that higher heat transfer is formed with the presence of Brownian and thermophoresis effect. In general, by considering the role of thermophoresis and Brownian motion, an enhancement in heat transfer is observed at any volume fraction of nanoparticles. However, the enhancement is more pronounced at low volume fraction of nanoparticles and the heat transfer decreases by increasing nanoparticle volume fraction. On the other hand, by neglecting the role of thermophoresis and Brownian motion, deterioration in heat transfer is observed and this deterioration elevates by increasing the volume fraction of nanoparticles.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/30987265" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="7a179a857bea87c5ffd400a80491d50d" rel="nofollow" data-download="{"attachment_id":51419571,"asset_id":30987265,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/51419571/download_file?st=MTczOTgxNzcyMCw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="18099532" href="https://independent.academia.edu/EAbuNada">Eiyad Abu-Nada</a><script data-card-contents-for-user="18099532" type="text/json">{"id":18099532,"first_name":"Eiyad","last_name":"Abu-Nada","domain_name":"independent","page_name":"EAbuNada","display_name":"Eiyad Abu-Nada","profile_url":"https://independent.academia.edu/EAbuNada?f_ri=187812","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_30987265 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="30987265"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 30987265, container: ".js-paper-rank-work_30987265", });

A two component non-homogenous equilibrium model is used for the nanofluid that incorporates the effects of Brownian motion and thermophoresis. Variable thermal conductivity and variable viscosity are taken into account in this work. Finite volume method is used to solve governing equations. Results are presented by streamlines, isotherms, nanoparticle distribution, local and mean Nusselt numbers and nanoparticle profiles at top and bottom side. Comparison of two cases as absence of Brownian and thermophoresis effects and presence of Brownian and thermophoresis effects showed that higher heat transfer is formed with the presence of Brownian and thermophoresis effect. In general, by considering the role of thermophoresis and Brownian motion, an enhancement in heat transfer is observed at any volume fraction of nanoparticles. However, the enhancement is more pronounced at low volume fraction of nanoparticles and the heat transfer decreases by increasing nanoparticle volume fraction. On the other hand, by neglecting the role of thermophoresis and Brownian motion, deterioration in heat transfer is observed and this deterioration elevates by increasing the volume fraction of nanoparticles.","downloadable_attachments":[{"id":51419571,"asset_id":30987265,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":18099532,"first_name":"Eiyad","last_name":"Abu-Nada","domain_name":"independent","page_name":"EAbuNada","display_name":"Eiyad
