The quadrilateral plate elements include the 4-node conforming plate element based on the classical laminate plate theory (CLPT), the 4-node and 9-node Mindlin plate element based on the first-order shear deformation laminated plate theory (FSDT), and a displacement-based 4-node quadrilateral element (RDKQ-NL20). Using the von-Karman’s large deflection theory and the total Lagrangian (TL) approach, the nonlinear FE governing equations for plate under thermal load are derived. Convergence analysis for four elements is first conducted. These elements are then used to predict the stable shapes of thermally-induced bistable plate. Numerical test shows that the plate element based on FSDT, namely the 4-node and 9-node Mindlin, and the RDKQ-NL20 plate element can predict two stable cylindrical shapes while the 4-node conforming plate predicts a saddles shape. Comparing the simulation results with ABAQUS, the RDKQ-NL20 element shows the best accuracy among all the elements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bistable" title="Bistable">Bistable</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=geometrical%20nonlinearity" title=" geometrical nonlinearity"> geometrical nonlinearity</a>, <a href="https://publications.waset.org/abstracts/search?q=quadrilateral%20plate%20elements" title=" quadrilateral plate elements"> quadrilateral plate elements</a> </p> <a href="https://publications.waset.org/abstracts/124454/finite-element-analysis-of-thermally-induced-bistable-plate-using-four-plate-elements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124454.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">220</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3912</span> Computation of Stress Intensity Factor Using Extended Finite Element Method </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoudi%20Noureddine">Mahmoudi Noureddine</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouregba%20Rachid"> Bouregba Rachid </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper the stress intensity factors of a slant-cracked plate of AISI 304 stainless steel, have been calculated using extended finite element method and finite element method (FEM) in ABAQUS software, the results were compared with theoretical values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stress%20intensity%20factors" title="stress intensity factors">stress intensity factors</a>, <a href="https://publications.waset.org/abstracts/search?q=extended%20finite%20element%20method" title=" extended finite element method"> extended finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=stainless%20steel" title=" stainless steel"> stainless steel</a>, <a href="https://publications.waset.org/abstracts/search?q=abaqus" title=" abaqus"> abaqus</a> </p> <a href="https://publications.waset.org/abstracts/22230/computation-of-stress-intensity-factor-using-extended-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22230.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">618</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3911</span> Discrete Element Modeling on Bearing Capacity Problems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Li">N.

In Belgium, partly due to poor insulation of the building stock, but certainly because of the massive use of fossil fuels for heating buildings, this share reaches almost 30%. To reduce carbon emissions from urban building heating, district heating networks emerge as a promising solution as they offer various assets such as improving the load factor, integrating combined heat and power systems, and enabling energy source diversification, including renewable sources and waste heat recovery. However, mainly for sake of simple operation, most existing district heating networks still operate at high or medium temperatures ranging between 120°C and 60°C (the socalled second and third-generations district heating networks). Although these district heating networks offer energy savings in comparison with individual boilers, such temperature levels generally require the use of fossil fuels (mainly natural gas) with combined heat and power. The fourth-generation district heating networks improve the transport and energy conversion efficiency by decreasing the operating temperature between 50°C and 30°C. Yet, to decarbonise the building heating one must increase the waste heat recovery and use mainly wind, solar or geothermal sources for the remaining heat supply. Fifth-generation networks operating between 35°C and 15°C offer the possibility to decrease even more the transport losses, to increase the share of waste heat recovery and to use electricity from renewable resources through the use of heat pumps to generate low temperature heat. The main objective of this contribution is to exhibit on a real-life test case the benefits of replacing an existing third-generation network by a fifth-generation one and to decarbonise the heat supply of the building stock. The second objective of the study is to highlight the difficulties resulting from the use of a fifth-generation, low-temperature, district heating network. To do so, a simulation model of the district heating network including its regulation is implemented in the modelling language Modelica. This model is applied to the test case of the heating network on the University of Liège's Sart Tilman campus, consisting of around sixty buildings. This model is validated with monitoring data and then adapted for low-temperature networks. A comparison of primary energy consumptions as well as CO2 emissions is done between the two cases to underline the benefits in term of energy independency and GHG emissions. To highlight the complexity of operating a lowtemperature network, the difficulty of adapting the mass flow rate to the heat demand is considered. This shows the difficult balance between the thermal comfort and the electrical consumption of the circulation pumps. Several control strategies are considered and compared to the global energy savings. The developed model can be used to assess the potential for energy and CO2 emissions savings retrofitting an existing network or when designing a new one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20simulation" title="building simulation">building simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=fifth-generation%20district%20heating%20network" title=" fifth-generation district heating network"> fifth-generation district heating network</a>, <a href="https://publications.waset.org/abstracts/search?q=low-temperature%20district%20heating%20network" title=" low-temperature district heating network"> low-temperature district heating network</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20building%20heating" title=" urban building heating"> urban building heating</a> </p> <a href="https://publications.waset.org/abstracts/170634/decarbonising-urban-building-heating-a-case-study-on-the-benefits-and-challenges-of-fifth-generation-district-heating-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170634.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3909</span> Finite Element Method as a Solution Procedure for Problems in Tissue Biomechanics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Momoh%20Omeiza%20Sheidu">Momoh Omeiza Sheidu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Finite element method as a method of providing solutions to problems in computational bio mechanics provides a framework for modeling the function of tissues that integrates structurally from cell to organ system and functionally across the physiological processes that affect tissue mechanics or are regulated by mechanical forces.

Bioenergy is currently the most widely used renewable energy, and agricultural waste is one of the main raw materials for bioenergy. In this study, we use orange peel residue, which is easier to collect from agricultural waste to produce bio-coal by torrefaction. The orange peel residue (with 25 to 30% moisture) was treated by torrefaction, and the experiments were conducted with initial temperature at room temperature (approximately at 25° C), with heating rates of 10, 30, and 50°C / min, with terminal temperatures at 150, 200, 250, 300, 350℃, and with residence time of 10, 20, and 30 minutes. The results revealed that the heating value, ash content and energy densification ratio of the solid products after torrefaction are in direct proportion to terminal temperatures and residence time, and are inversely proportional to heating rates. The moisture content, solid mass yield, energy yield, and volumetric energy density of the solid products after torrefaction are inversely proportional to terminal temperatures and residence time, and are in direct proportion to heating rates. In conclusion, we found that the heating values of the solid products were 1.3 times higher than those of the raw orange peels before torrefaction, and the volumetric energy densities were increased by 1.45 times under operating parameters with terminal temperature at 250°C, residence time of 10 minutes, and heating rate of 10°C / min of torrefaction. The results indicated that the residue of orange peel treated by torrefaction improved its energy density and fuel properties, and became more suitable for bio-fuel applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass%20energy" title="biomass energy">biomass energy</a>, <a href="https://publications.waset.org/abstracts/search?q=orange" title=" orange"> orange</a>, <a href="https://publications.waset.org/abstracts/search?q=torrefaction" title=" torrefaction"> torrefaction</a> </p> <a href="https://publications.waset.org/abstracts/65085/a-feasibility-study-on-producing-bio-coal-from-orange-peel-residue-by-using-torrefaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65085.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">289</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3907</span> Wave Interaction with Defects in Pressurized Composite Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20K.%20Apalowo">R.

The structural system is discretized as a system comprising a number of waveguides connected by a coupling joint. Uniform nodes are ensured at the interfaces of the coupling element with each waveguide. Then, equilibrium and continuity conditions are enforced at the interfaces. Wave propagation properties of each waveguide are calculated using the WFE method and the coupling element is modelled using the FE method. The scattering of waves through the coupling element, on which damage is modelled, is determined by coupling the FE and WFE models. Furthermore, the central aim is to evaluate the effect of pressurization on the wave dispersion and scattering characteristics of the prestressed structural system compared to that which is not prestressed. Numerical case studies are exhibited for two waveguides coupled through a coupling joint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Finite%20Element" title="Finite Element">Finite Element</a>, <a href="https://publications.waset.org/abstracts/search?q=Prestressed%20Structures" title=" Prestressed Structures"> Prestressed Structures</a>, <a href="https://publications.waset.org/abstracts/search?q=Wave%20Finite%20Element" title="Wave Finite Element">Wave Finite Element</a>, <a href="https://publications.waset.org/abstracts/search?q=Wave%20Propagation%20Properties" title=" Wave Propagation Properties"> Wave Propagation Properties</a>, <a href="https://publications.waset.org/abstracts/search?q=Wave%20Scattering%20Coefficients." title=" Wave Scattering Coefficients."> Wave Scattering Coefficients.</a> </p> <a href="https://publications.waset.org/abstracts/58482/wave-interaction-with-defects-in-pressurized-composite-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58482.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">295</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3906</span> Present an Active Solar Energy System to Supply Heating Demands of the Teaching Staff Dormitory of Islamic Azad University of Ramhormoz</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Talebzadegan">M.

The design takes into account the solar radiations and climate data of Ramhormoz town and is based on the daily warm water consumption for health demands of 450 residents of the dormitory, which is equal to 27000 lit of 50 C° water, and building heating requirements with an area of 3500 m² well-protected by heatproof materials. First, heating demands of the building were calculated, then a hybrid system made up of solar and fossil energies was developed and finally, the design was economically evaluated. Since there is only roof space for using 110 flat solar water heaters, the calculations were made to hybridize solar water heating system with heat pumping system in which solar energy contributes 67% of the heat generated. According to calculations, the Net Present Value “N.P.V.” of revenue stream exceeds “N.P.V.” of cash paid off in this project over three years, which makes economically quite promising. The return of investment and payback period of the project is 4 years. Also, the Internal Rate of Return (IRR) of the project was 25%, which exceeds bank rate of interest in Iran and emphasizes the desirability of the project. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title="solar energy">solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20demand" title=" heat demand"> heat demand</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable" title=" renewable"> renewable</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a> </p> <a href="https://publications.waset.org/abstracts/30693/present-an-active-solar-energy-system-to-supply-heating-demands-of-the-teaching-staff-dormitory-of-islamic-azad-university-of-ramhormoz" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30693.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">420</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3905</span> Viability Study of the Use of Solar Energy for Water Heating in Homes in Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elmo%20Thiago%20Lins%20C%C3%B6uras%20Ford">Elmo Thiago Lins Cöuras Ford</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Alessandra%20Carvalho%20do%20Vale"> Valentina Alessandra Carvalho do Vale</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The sun is an inexhaustible source and harnessing its potential both for heating and for power generation is one of the most promising and necessary alternatives, mainly due to environmental issues. However, it should be noted that this has always been present in the generation of energy on the planet, only indirectly, as it is responsible for virtually all other energy sources, such as: Generates the evaporation source of the water cycle, which allows the impoundment and the consequent generation of electricity (hydroelectricity); Winds are caused by large-scale atmospheric induction caused by solar radiation; Oil, coal and natural gas were generated from waste plants and animals that originally obtained the energy needed for its development of solar radiation. Thus, the idea of using solar energy for practical purposes for the benefit of man is not new, as it accompanies the story since the beginning of time, which means that the sun was always of utmost importance in the design of shelters, or homes is, constructed by taking into consideration the use of sunlight, practicing what was being lost through the centuries, until a time when the buildings started to be designed completely independent of the sun. However, the climatic rigors still needed to be fought, only artificially and today seen as unsustainable, with additional facilities fueled by energy consumption. This paper presents a study on the feasibility of using solar energy for heating water in homes, developing a simplified methodology covering the mode of operation of solar water heaters, solar potential existing alternative systems of Brazil, the international market, and barriers encountered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title="solar energy">solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20heating" title=" solar heating"> solar heating</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20project" title=" solar project"> solar project</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20heating" title=" water heating"> water heating</a> </p> <a href="https://publications.waset.org/abstracts/19288/viability-study-of-the-use-of-solar-energy-for-water-heating-in-homes-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19288.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3904</span> Aerothermal Analysis of the Brazilian 14-X Hypersonic Aerospace Vehicle at Mach Number 7</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Felipe%20J.%20Costa">Felipe J.

Nagamatsu Laboratory of Aerothermodynamics and Hypersonics, at the Institute for Advanced Studies designed the Brazilian 14-X Hypersonic Aerospace Vehicle, which is a technological demonstrator endowed with two innovative technologies: waverider technology, to obtain lift from conical shockwave during the hypersonic flight; and uses hypersonic airbreathing propulsion system called scramjet that is based on supersonic combustion, to perform flights on Earth's atmosphere at 30 km altitude at Mach numbers 7 and 10. The scramjet is an aeronautical engine without moving parts that promote compression and deceleration of freestream atmospheric air at the inlet through the conical/oblique shockwaves generated during the hypersonic flight. During high speed flight, the shock waves and the viscous forces yield the phenomenon called aerodynamic heating, where this physical meaning is the friction between the fluid filaments and the body or compression at the stagnation regions of the leading edge that converts the kinetic energy into heat within a thin layer of air which blankets the body. The temperature of this layer increases with the square of the speed. This high temperature is concentrated in the boundary-layer, where heat will flow readily from the boundary-layer to the hypersonic aerospace vehicle structure. Fay and Riddell and Eckert methods are applied to the stagnation point and to the flat plate segments in order to calculate the aerodynamic heating. On the understanding of the aerodynamic heating it is important to analyze the heat conduction transfer to the 14-X waverider internal structure. ANSYS Workbench software provides the Thermal Numerical Analysis, using Finite Element Method of the 14-X waverider unpowered scramjet at 30 km altitude at Mach number 7 and 10 in terms of temperature and heat flux. Finally, it is possible to verify if the internal temperature complies with the requirements for embedded systems, and, if is necessary to do modifications on the structure in terms of wall thickness and materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20heating" title="aerodynamic heating">aerodynamic heating</a>, <a href="https://publications.waset.org/abstracts/search?q=hypersonic" title=" hypersonic"> hypersonic</a>, <a href="https://publications.waset.org/abstracts/search?q=scramjet" title=" scramjet"> scramjet</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20analysis" title=" thermal analysis"> thermal analysis</a> </p> <a href="https://publications.waset.org/abstracts/59514/aerothermal-analysis-of-the-brazilian-14-x-hypersonic-aerospace-vehicle-at-mach-number-7" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">452</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3903</span> Study of Heat Transfer through the Ground and its Accumulation Properties to Increase the Energy Efficiency of Underground Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandeep%20Bandarwadkar">Sandeep Bandarwadkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadas%20Zdankus"> Tadas Zdankus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To maintain a comfortable indoor temperature for its residents in the colder season, heating a building is necessary. Due to the expansion in the construction sectors, the consumption of heating energy is increasing. According to Eurostat data, in the European Union, the share of energy consumption of heating energy for space and cooling in residential buildings was around 63% in 2019. These figures indicate that heating energy still accounts for a significant portion of total energy consumption in Europe. Innovation is crucial to reduce energy consumption in buildings and achieve greater energy efficiency and sustainability. It can bring about new solutions that are smarter and more natural energy generation to reduce greenhouse gas emissions. The ground can serve as an effective and sustainable heat accumulator for heating and cooling. The temperature of the ground is higher than that of the ambient air in the colder period and lower in the warmer period. The building deep in the soil could use less thermal energy compared to the above-ground buildings that provide the same amount of thermal comfort. The temperature difference between the soil and the air inside the building decreases as the temperature of the soil increases. In progress, this process generates the condition that acts against heat loss. However, heat dissipates further to the consecutive layers and reaches thermal equilibrium. The charging of the ground by heat and its dissipation through the adjacent soil layers was investigated experimentally. The results of this research showed that 9% of the energy savings in partially underground buildings and 44.4% in completely underground buildings were derived from heating the space. Heat loss to the ground is treated as a charge of the soil by thermal energy. The dependence of the intensity of the charge on time was analysed and presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title="heat transfer">heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=accumulation%20of%20heat" title=" accumulation of heat"> accumulation of heat</a>, <a href="https://publications.waset.org/abstracts/search?q=underground%20building" title=" underground building"> underground building</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20charge" title=" soil charge"> soil charge</a> </p> <a href="https://publications.waset.org/abstracts/165507/study-of-heat-transfer-through-the-ground-and-its-accumulation-properties-to-increase-the-energy-efficiency-of-underground-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165507.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">71</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3902</span> FEM Simulations to Study the Effects of Laser Power and Scan Speed on Molten Pool Size in Additive Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yee-Ting%20Lee">Yee-Ting Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jyun-Rong%20Zhuang"> Jyun-Rong Zhuang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Hsin%20Hsieh"> Wen-Hsin Hsieh</a>, <a href="https://publications.waset.org/abstracts/search?q=An-Shik%20Yang"> An-Shik Yang </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Additive manufacturing (AM) is increasingly crucial in biomedical and aerospace industries. As a recently developed AM technique, selective laser melting (SLM) has become a commercial method for various manufacturing processes. However, the molten pool configuration during SLM of metal powders is a decisive issue for the product quality. It is very important to investigate the heat transfer characteristics during the laser heating process. In this work, the finite element method (FEM) software ANSYS<sup>®</sup> (work bench module 16.0) was used to predict the unsteady temperature distribution for resolving molten pool dimensions with consideration of temperature-dependent thermal physical properties of TiAl6V4 at different laser powers and scanning speeds. The simulated results of the temperature distributions illustrated that the ratio of laser power to scanning speed can greatly influence the size of molten pool of titanium alloy powder for SLM development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=molten%20pool%20dimensions" title=" molten pool dimensions"> molten pool dimensions</a>, <a href="https://publications.waset.org/abstracts/search?q=selective%20laser%20melting" title=" selective laser melting"> selective laser melting</a> </p> <a href="https://publications.waset.org/abstracts/66793/fem-simulations-to-study-the-effects-of-laser-power-and-scan-speed-on-molten-pool-size-in-additive-manufacturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66793.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3901</span> Performance of a Solar Heating System on the Microclimate of an Agricultural Greenhouse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nora%20Arbaoui">Nora Arbaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Tadili"> Rachid Tadili</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilham%20Ihoume"> Ilham Ihoume</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate change and its effects on low external temperatures in winter require great consumption of energy to improve the greenhouse microclimate and increase agricultural production. To reduce the amount of energy consumed, a solar system has been developed to heat an agricultural greenhouse. This system is based on a transfer fluid that will circulate inside the greenhouse through a solar copper coil positioned on the roof of the greenhouse. This thermal energy accumulated during the day will be stored to be released during the night to improve the greenhouse’s microclimate. The use of this solar heating system has resulted in an average increase in the greenhouse’s indoor temperature of 8.3°C compared to the outdoor environment. This improved temperature has created a more favorable climate for crops and has subsequently had a positive effect on their development, quality, and production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20system" title="solar system">solar system</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20greenhouse" title=" agricultural greenhouse"> agricultural greenhouse</a>, <a href="https://publications.waset.org/abstracts/search?q=heating" title=" heating"> heating</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling" title=" cooling"> cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=storage" title=" storage"> storage</a>, <a href="https://publications.waset.org/abstracts/search?q=drying" title=" drying"> drying</a> </p> <a href="https://publications.waset.org/abstracts/161297/performance-of-a-solar-heating-system-on-the-microclimate-of-an-agricultural-greenhouse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161297.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3900</span> Numerical Analysis of Multiplicity and Transition Phenomena in Natural Convection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Kafil">Hadi Kafil</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ecder"> Ali Ecder</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heat transfer by natural convection in two-dimensional and three-dimensional axisymmetric enclosure fitted with partially heated vertical walls is investigated numerically.

The coffee grounds were tested as an additive for pelletizing process of bagasse pellets. Pelletizing was performed using a Flat–die pellet mill machine. Moisture content of raw materials was controlled at 10-13%. Die temperature range during the process was 75-80 <sup>o</sup>C. Physical characteristics (bulk density and durability) of the bagasse pellet and pellets with 1-5% coffee ground were determined following the standard assigned by the Pellet Fuel Institute (PFI). The results revealed increasing values of 648±3.4, 659 ± 3.1, 679 ± 3.3 and 685 ± 3.1 kg/m<sup>3</sup> (for pellet bulk density); and 98.7 ± 0.11, 99.2 ± 0.26, 99.3 ± 0.19 and 99.4 ± 0.07% (for pellet durability), respectively. In addition, the heating values of the coffee ground supplemented pellets (15.9 ± 1.16, 17.0 ± 1.23 and 18.8 ± 1.34 MJ/kg) were improved comparing to the non-supplemented control (14.9 ± 1.14 MJ/kg), respectively. The results indicated that both the bulk density and durability values of the bagasse pellets were increased with the increasing proportion of the coffee ground additive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bagasse" title="bagasse">bagasse</a>, <a href="https://publications.waset.org/abstracts/search?q=coffee%20grounds" title=" coffee grounds"> coffee grounds</a>, <a href="https://publications.waset.org/abstracts/search?q=pelletizing" title=" pelletizing"> pelletizing</a>, <a href="https://publications.waset.org/abstracts/search?q=heating%20value" title=" heating value"> heating value</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar%20cane%20bagasse" title=" sugar cane bagasse"> sugar cane bagasse</a> </p> <a href="https://publications.waset.org/abstracts/90942/effect-of-coffee-grounds-on-physical-and-heating-value-properties-of-sugarcane-bagasse-pellets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90942.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3898</span> Modelling Kinetics of Colour Degradation in American Pokeweed (Phytolacca americana) Extract Concentration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed-Ahmad%20Shahidi">Seyed-Ahmad Shahidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Salemeh%20Kazemzadeh"> Salemeh Kazemzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Sharifi%20Soltani"> Mehdi Sharifi Soltani</a>, <a href="https://publications.waset.org/abstracts/search?q=Azade%20Ghorbani-HasanSaraei"> Azade Ghorbani-HasanSaraei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The kinetics of colour changes of American Pokeweed extract, due to concentration by various heating methods was studied. Three different heating/evaporation processes were employed for production of American Pokeweed extract concentrate. The American Pokeweed extract was concentrated to a final 40 °Brix from an initial °Brix of 4 by microwave heating, rotary vacuum evaporator and evaporating at atmospheric pressure. The final American Pokeweed extract concentration of 40 °Brix was achieved in 188, 216 and 320 min by using microwave, rotary vacuum and atmospheric heating processes, respectively. The colour change during concentration processes was investigated. Total colour differences, Hunter L, a and b parameters were used to estimate the extent of colour loss. All Hunter colour parameters decreased with time. The zero-order, first-order and a combined kinetics model were applied to the changes in colour parameters. All models were found to describe the L, a and b-data adequately. Results indicated that variation in TCD followed both first-order and combined kinetics models.

The design takes into account the solar radiations and climate data of Ramhormoz town and is based on the daily warm water consumption for health demands of 450 residents of the dormitory, which is equal to 27000 lit of 50-C° water, and building heating requirements with an area of 3500 m² well-protected by heatproof materials. First, heating demands of the building were calculated, then a hybrid system made up of solar and fossil energies was developed and finally, the design was economically evaluated. Since there is only roof space for using 110 flat solar water heaters, the calculations were made to hybridize solar water heating system with heat pumping system in which solar energy contributes 67% of the heat generated. According to calculations, the net present value “N.P.V.” of revenue stream exceeds “N.P.V.” of cash paid off in this project over three years, which makes economically quite promising. The return of investment and payback period of the project is 4 years. Also, the internal rate of return (IRR) of the project was 25%, which exceeds bank rate of interest in Iran and emphasizes the desirability of the project. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Solar%20energy" title="Solar energy">Solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=Heat%20Demand" title=" Heat Demand"> Heat Demand</a>, <a href="https://publications.waset.org/abstracts/search?q=Renewable" title=" Renewable "> Renewable </a>, <a href="https://publications.waset.org/abstracts/search?q=Pollution" title=" Pollution"> Pollution</a> </p> <a href="https://publications.waset.org/abstracts/36610/an-active-solar-energy-system-to-supply-heating-demands-of-the-teaching-staff-dormitory-of-islamic-azad-university-ramhormoz-branch" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36610.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">252</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3893</span> Study of the Effect of Voltage and PH on the Inactivation of Byssochlamys fulva in Tomato Juice by Ohmic Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Dara">Arash Dara</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Mokhtari"> Mahsa Mokhtari</a>, <a href="https://publications.waset.org/abstracts/search?q=Nafiseh%20Zamindar"> Nafiseh Zamindar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to determine the effect of thermal resistance, temperature, voltage, and pH changes in an ohmic heating system on reducing the logarithmic number of Byssochlamys fulva species (PTCC 5062) in tomato juice water and to investigate the quantitative properties of tomato juice in the ohmic heating pasteurization system. The percentage of thermal degradation by ohmic heating was determined in tomato juice for the kinetics of Byssochlamys fulva in ohmic chamber at the temperatures of 88, 93, and 98°C, with two voltages of 30 and 40 volts and two pH levels of 3.5 and 4.5; this was done using Weibull frequency distribution model. Three different parameters (pH = 3.5, two voltages of 30 and 40, at three temperatures 88, 93, and 98) and (pH = 4.5, two voltages 30 and 40, at three temperatures 88, 93, and 98) in three replications were considered in the ohmic system. Heating time for the temperature of 88°C was 20 minutes once every 2 minutes, while for the temperature of 93°C, it was 10 minutes once every 1 minute. At the temperature of 98°C, the first time was 0.5 minutes, and for other times, sampling was done every 1 minute. In each condition, the qualitative characteristics, including acidity, Brix, and pH, were measured before and after the ohmic process in the tomato juice. This study demonstrates that the differences in pH and voltage due to different temperatures in the ohmic process can greatly affect the inactivation of Byssochlamys fulva fungus and the qualitative characteristics of the tomato juice. This is the first study using the Weibull frequency method to model the inactivation of Byssochlamys fulva in tomato juice. Variation in parameters such as temperature, voltage, and pH can prevent the presence of Byssochlamys fulva in the pasteurized juices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pasteurization" title="pasteurization">pasteurization</a>, <a href="https://publications.waset.org/abstracts/search?q=ohmic%20heating%20process" title=" ohmic heating process"> ohmic heating process</a>, <a href="https://publications.waset.org/abstracts/search?q=Byssochlamys%20fulva" title=" Byssochlamys fulva"> Byssochlamys fulva</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato%20juice" title=" tomato juice"> tomato juice</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20resistance" title=" heat resistance"> heat resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage" title=" voltage"> voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=pH" title=" pH"> pH</a> </p> <a href="https://publications.waset.org/abstracts/136482/study-of-the-effect-of-voltage-and-ph-on-the-inactivation-of-byssochlamys-fulva-in-tomato-juice-by-ohmic-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136482.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3892</span> Machine Learning Models for the Prediction of Heating and Cooling Loads of a Residential Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aaditya%20U.%20Jhamb">Aaditya U. Jhamb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the current energy crisis that many countries are battling, energy-efficient buildings are the subject of extensive research in the modern technological era because of growing worries about energy consumption and its effects on the environment. The paper explores 8 factors that help determine energy efficiency for a building: (relative compactness, surface area, wall area, roof area, overall height, orientation, glazing area, and glazing area distribution), with Tsanas and Xifara providing a dataset. The data set employed 768 different residential building models to anticipate heating and cooling loads with a low mean squared error. By optimizing these characteristics, machine learning algorithms may assess and properly forecast a building's heating and cooling loads, lowering energy usage while increasing the quality of people's lives. As a result, the paper studied the magnitude of the correlation between these input factors and the two output variables using various statistical methods of analysis after determining which input variable was most closely associated with the output loads. The most conclusive model was the Decision Tree Regressor, which had a mean squared error of 0.258, whilst the least definitive model was the Isotonic Regressor, which had a mean squared error of 21.68. This paper also investigated the KNN Regressor and the Linear Regression, which had to mean squared errors of 3.349 and 18.141, respectively. In conclusion, the model, given the 8 input variables, was able to predict the heating and cooling loads of a residential building accurately and precisely. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20efficient%20buildings" title="energy efficient buildings">energy efficient buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=heating%20load" title=" heating load"> heating load</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling%20load" title=" cooling load"> cooling load</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning%20models" title=" machine learning models"> machine learning models</a> </p> <a href="https://publications.waset.org/abstracts/165611/machine-learning-models-for-the-prediction-of-heating-and-cooling-loads-of-a-residential-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165611.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3891</span> Effects of Using Alternative Energy Sources and Technologies to Reduce Energy Consumption and Expenditure of a Single Detached House</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gul%20Nihal%20Gugul">Gul Nihal Gugul</a>, <a href="https://publications.waset.org/abstracts/search?q=Merih%20Aydinalp-Koksal"> Merih Aydinalp-Koksal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, hourly energy consumption model of a single detached house in Ankara, Turkey is developed using ESP-r building energy simulation software. Natural gas is used for space heating, cooking, and domestic water heating in this two story 4500 square feet four-bedroom home. Hourly electricity consumption of the home is monitored by an automated meter reading system, and daily natural gas consumption is recorded by the owners during 2013. Climate data of the region and building envelope data are used to develop the model. The heating energy consumption of the house that is estimated by the ESP-r model is then compared with the actual heating demand to determine the performance of the model. Scenarios are applied to the model to determine the amount of reduction in the total energy consumption of the house. The scenarios are using photovoltaic panels to generate electricity, ground source heat pumps for space heating and solar panels for domestic hot water generation. Alternative scenarios such as improving wall and roof insulations and window glazing are also applied. These scenarios are evaluated based on annual energy, associated CO2 emissions, and fuel expenditure savings. The pay-back periods for each scenario are also calculated to determine best alternative energy source or technology option for this home to reduce annual energy use and CO2 emission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ESP-r" title="ESP-r">ESP-r</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20energy%20simulation" title=" building energy simulation"> building energy simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20energy%20saving" title=" residential energy saving"> residential energy saving</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20reduction" title=" CO2 reduction"> CO2 reduction</a> </p> <a href="https://publications.waset.org/abstracts/53463/effects-of-using-alternative-energy-sources-and-technologies-to-reduce-energy-consumption-and-expenditure-of-a-single-detached-house" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53463.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">199</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3890</span> Effect of Elevated Temperatures on Trans Fat Content and Oxidative Parameters of Groundnut Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akanksha%20Jain">Akanksha Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Santosh%20J.%20Passi"> Santosh J.

The present study was designed to assess the effect of constant heating/frying on formation of TFAs and oxidative stability in groundnut oil. 750 mL of the oil was heated in a large iron karahi (utensil similar to a wok) and freshly cut potato strips were fried constantly at varying temperatures (160ºC, 180ºC, 200ºC, 220ºC, 230ºC). In each case, the oil sample was drawn after one hour and stored at –20ºC until analysed. While TFA was estimated using gas chromatography with flame ionisation detector (AOCS official method Ce 1h–05), other chemical parameters were assessed by AOCS official methods. Oil samples subjected to heating/frying at varying temperatures demonstrated a significant increase in TFAs (p < 0.01) and saturated fatty acids (p < 0.01) while there was a corresponding decrease in cis-unsaturated fatty acids (p < 0.01). Frying process demonstrated greater TFA formation (mean TFA at 160ºC being 0.11±0.01g/100g; at 230ºC it being 2.33±0.05g/100g) as compared to heating alone (mean TFA at 160ºC being 0.07g±0.01/100g; at 230ºC it being 0.47±0.02g/100g), indicating that there was a significant difference in the generation of TFAs during the two thermal treatments (heating vs. frying; p=0.05). With increasing temperatures, acid value, p-anisidine value and total oxidation (TOTOX) value registered a significant increase (p < 0.01); however, peroxide value was found to be inconsistent. Thus, the formation of TFA and various oxidative parameters (except peroxide value) is directly influenced by the temperature of heating/frying. Since TFA formation and poor oxidative stability of oils can pose serious health concerns, food safety agencies/organizations need to devise appropriate policies, stringent food laws/standards and impose necessary safety regulations to curb oil abuse during the process of heating and frying. There is a dire need to raise consumer awareness regarding deleterious health effects of TFA and oxidative deterioration of oils at elevated temperatures employed during heating/frying procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cis-unsaturated%20fatty%20acid" title="cis-unsaturated fatty acid">cis-unsaturated fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stability" title=" oxidative stability"> oxidative stability</a>, <a href="https://publications.waset.org/abstracts/search?q=saturated%20fatty%20acid" title=" saturated fatty acid"> saturated fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=trans%20fatty%20acid" title=" trans fatty acid"> trans fatty acid</a> </p> <a href="https://publications.waset.org/abstracts/95093/effect-of-elevated-temperatures-on-trans-fat-content-and-oxidative-parameters-of-groundnut-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95093.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3889</span> Effects from Maillard Reactions on the Alleginicity of Peanuts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khadija%20Radhi">Khadija Radhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Food allergy is a serious public health problem, especially in developed countries. As one of the most significant allergies, peanut allergy was investigated in this research. Peanut was mixed with treacle under different heating conditions. The results of glycation analyses revealed that proteins from peanuts interacted with the carbohydrates. Further studies also indicated that Millard reactions were determined by different heating treatment. It is noted that denatured peanut proteins accelerated the first stage of Millard reactions but prevented the third one. From the ELISA results, it was found that Millard reactions between proteins with sugars had no effects on the allergenicity of peanuts. Besides, there was no significant difference in allergenicity between digested and non-digested peanut proteins. However, pre-boiled peanut with denatured proteins displayed lower allergenicity after mixing with sugars. Such results indicated that denaturation is the key factor to reduce the allergenicity of the peanut proteins and it seemed that the second-staged Maillard products had less allergenicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=allergenicity" title="allergenicity">allergenicity</a>, <a href="https://publications.waset.org/abstracts/search?q=heating%20treatment" title=" heating treatment"> heating treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=peanut" title=" peanut"> peanut</a>, <a href="https://publications.waset.org/abstracts/search?q=Maillard%20reaction" title=" Maillard reaction"> Maillard reaction</a> </p> <a href="https://publications.waset.org/abstracts/18275/effects-from-maillard-reactions-on-the-alleginicity-of-peanuts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18275.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">333</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3888</span> Feasibility Study for Implementation of Geothermal Energy Technology as a Means of Thermal Energy Supply for Medium Size Community Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sreto%20Boljevic">Sreto Boljevic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heating systems based on geothermal energy sources are becoming increasingly popular among commercial/community buildings as management of these buildings looks for a more efficient and environmentally friendly way to manage the heating system. The thermal energy supply of most European commercial/community buildings at present is provided mainly by energy extracted from natural gas. In order to reduce greenhouse gas emissions and achieve climate change targets set by the EU, restructuring in the area of thermal energy supply is essential. At present, heating and cooling account for approx... 50% of the EU primary energy supply. Due to its physical characteristics, thermal energy cannot be distributed or exchange over long distances, contrary to electricity and gas energy carriers. Compared to electricity and the gas sectors, heating remains a generally black box, with large unknowns to a researcher and policymaker. Ain literature number of documents address policies for promoting renewable energy technology to facilitate heating for residential/community/commercial buildings and assess the balance between heat supply and heat savings. Ground source heat pump (GSHP) technology has been an extremely attractive alternative to traditional electric and fossil fuel space heating equipment used to supply thermal energy for residential/community/commercial buildings. The main purpose of this paper is to create an algorithm using an analytical approach that could enable a feasibility study regarding the implementation of GSHP technology in community building with existing fossil-fueled heating systems. The main results obtained by the algorithm will enable building management and GSHP system designers to define the optimal size of the system regarding technical, environmental, and economic impacts of the system implementation, including payback period time. In addition, an algorithm is created to be utilized for a feasibility study for many different types of buildings. The algorithm is tested on a building that was built in 1930 and is used as a church located in Cork city. The heating of the building is currently provided by a 105kW gas boiler. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GSHP" title="GSHP">GSHP</a>, <a href="https://publications.waset.org/abstracts/search?q=greenhouse%20gas%20emission" title=" greenhouse gas emission"> greenhouse gas emission</a>, <a href="https://publications.waset.org/abstracts/search?q=low-enthalpy" title=" low-enthalpy"> low-enthalpy</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/134947/feasibility-study-for-implementation-of-geothermal-energy-technology-as-a-means-of-thermal-energy-supply-for-medium-size-community-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134947.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">219</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3887</span> Indoor Emissions Produced by Kerosene Heating, Determining Its Formation Potential of Secondary Particulate Matter and Transport</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20M.%20Mu%C3%B1oz">J.

It will be expected watch a contaminants transport from outside to inside of the household and the kerosene emissions present a high potential of formation secondary particulate matter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heating" title="heating">heating</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20pollution" title=" indoor pollution"> indoor pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=kerosene" title=" kerosene"> kerosene</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20particulate%20matter" title=" secondary particulate matter"> secondary particulate matter</a> </p> <a href="https://publications.waset.org/abstracts/73230/indoor-emissions-produced-by-kerosene-heating-determining-its-formation-potential-of-secondary-particulate-matter-and-transport" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73230.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">216</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3886</span> Integration of Thermal Energy Storage and Electric Heating with Combined Heat and Power Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erich%20Ryan">Erich Ryan</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20McDaniel"> Benjamin McDaniel</a>, <a href="https://publications.waset.org/abstracts/search?q=Dragoljub%20Kosanovic"> Dragoljub Kosanovic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Combined heat and power (CHP) plants are an efficient technology for meeting the heating and electric needs of large campus energy systems, but have come under greater scrutiny as the world pushes for emissions reductions and lower consumption of fossil fuels. The electrification of heating and cooling systems offers a great deal of potential for carbon savings, but these systems can be costly endeavors due to increased electric consumption and peak demand. Thermal energy storage (TES) has been shown to be an effective means of improving the viability of electrified systems, by shifting heating and cooling load to off-peak hours and reducing peak demand charges. In this study, we analyze the integration of an electrified heating and cooling system with thermal energy storage into a campus CHP plant, to investigate the potential of leveraging existing infrastructure and technologies with the climate goals of the 21st century. A TRNSYS model was built to simulate a ground source heat pump (GSHP) system with TES using measured campus heating and cooling loads. The GSHP with TES system is modeled to follow the parameters of industry standards and sized to provide an optimal balance of capital and operating costs. Using known CHP production information, costs and emissions were investigated for a unique large energy user rate structure that operates a CHP plant. The results highlight the cost and emissions benefits of a targeted integration of heat pump technology within the framework of existing CHP systems, along with the performance impacts and value of TES capability within the combined system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20energy%20storage" title="thermal energy storage">thermal energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=combined%20heat%20and%20power" title=" combined heat and power"> combined heat and power</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20pumps" title=" heat pumps"> heat pumps</a>, <a href="https://publications.waset.org/abstracts/search?q=electrification" title=" electrification"> electrification</a> </p> <a href="https://publications.waset.org/abstracts/149506/integration-of-thermal-energy-storage-and-electric-heating-with-combined-heat-and-power-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149506.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3885</span> Transient Analysis of Laminated Rubber Bearing Bridge during High Intensity Earthquake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20M.%20Amin">N.

At present, the studies of the numerical modelling using 3D solid element are minimal due to numerical software constraint. The finite element analysis using 3D solid element was chosen to study displacement response of laminated rubber bearing (LRB) during high intensity Kobe earthquake. In this research a simply supported bridge (single span), fixed at support was analysed by using transient analysis subjected to real time history loading of Kobe earthquake. <p
