Diﬀerent from the classical shooting methodology, we employ a combination of a direct and an iterative method (SOR with optimal relaxation parameter) for solving the sparse systems of linear algebraic equations arising from the FD discretization of the linearized self similar nonlinear ODEs. Eﬀects of the governing parameters on the ﬂow and heat transfer are discussed and presented through tables and graphs.

The fluid flow is considered as a laminar regime. A constant heat flux is applied on the microtube outer wall and the two ends of its wall are considered adiabatic. Conjugate heat transfer problem is solved and investigated for this geometry. It is shown that viscous dissipation effect which is induced by shear stresses can not be neglected in microtubes. Viscous heating behaves as an energy source in the fluid and affects the temperature distribution. The effect of Reynolds number, particle volume fraction and the nanoparticles diameter on the energy source are investigated and an attempt on establishing suitable equations for assessing the value of the energy source based on Re, Dp and Φ is performed and they are depicted as 3D diagrams. Finally, the significance of viscous dissipation and the influence of these parameters on convective heat transfer coefficient are studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convective%20heat%20transfer%20coefficient" title="convective heat transfer coefficient">convective heat transfer coefficient</a>, <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=microtube" title=" microtube"> microtube</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofluid" title=" nanofluid"> nanofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=viscous%20dissipation" title=" viscous dissipation"> viscous dissipation</a> </p> <a href="https://publications.waset.org/abstracts/15475/numerical-investigation-of-al2o3water-nanofluid-heat-transfer-in-a-microtube-with-viscous-dissipation-effect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15475.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">512</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">1309</span> Quantom Magnetic Effects of P-B Fusion in Plasma Focus Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Habibi">M. Habibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The feasibility of proton-boron fusion in plasmoids caused by magneto hydrodynamics instabilities in plasma focus devices is studied analytically. In plasmoids, fusion power for 76 keV < Ti < 1500 keV exceeds bremsstrahlung loss (W/Pb=5.39). In such situation gain factor and the ratio of Te to Ti for a typical 150 kJ plasma focus device will be 7.8 and 4.8 respectively. Also with considering the ion viscous heating effect, W/Pb and Ti/Te will be 2.7 and 6 respectively. Strong magnetic field will reduces ion-electron collision rate due to quantization of electron orbits. While approximately there is no change in electron-ion collision rate, the effect of quantum magnetic field makes ions much hotter than electrons which enhance the fraction of fusion power to bremsstrahlung loss. Therefore self-sustained p-11B fusion reactions would be possible and it could be said that p-11B fuelled plasma focus device is a clean and efficient source of energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plasmoids" title="plasmoids">plasmoids</a>, <a href="https://publications.waset.org/abstracts/search?q=p11B%20fuel" title=" p11B fuel"> p11B fuel</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20viscous%20heating" title=" ion viscous heating"> ion viscous heating</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20magnetic%20field" title=" quantum magnetic field"> quantum magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20focus%20device" title=" plasma focus device"> plasma focus device</a> </p> <a href="https://publications.waset.org/abstracts/26776/quantom-magnetic-effects-of-p-b-fusion-in-plasma-focus-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26776.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">463</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">1308</span> Vibration Analysis of Pendulum in a Viscous Fluid by Analytical Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Jafari">Arash Jafari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Taghaddosi"> Mehdi Taghaddosi</a>, <a href="https://publications.waset.org/abstracts/search?q=Azin%20Parvin"> Azin Parvin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a vibrational differential equation governing on swinging single-degree-of-freedom pendulum in a viscous fluid has been investigated.

The mathematical analysis of this problem in most cases is very difficult and it is reduced to simple cases. Another knowledge of induction heating systems is generated in production environments, but these trial-error procedures are long and expensive. The numerical models of induction heating problem are another approach to reduce abovementioned drawbacks. This paper deals with the simulation model of induction heating problem. The simulation model of induction heating system in COMSOL Multiphysics is created. In this work we present results of numerical simulations of induction heating process in pieces of cylindrical shapes, in an inductor with four coils.

Then this paper analyses the changes of indoor temperature of these two systems, finding out the differences between all-air heating system and radiant floor heating system to help the designer choose a more suitable heating system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radiant%20floor" title="radiant floor">radiant floor</a>, <a href="https://publications.waset.org/abstracts/search?q=all-air%20system" title=" all-air system"> all-air system</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title=" thermal comfort"> thermal comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=heating%20system" title=" heating system"> heating system</a> </p> <a href="https://publications.waset.org/abstracts/109700/simulation-study-on-comparison-of-thermal-comfort-during-heating-with-all-air-system-and-radiant-floor-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109700.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">165</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">1302</span> Life Cycle Cost Evaluation of Structures Retrofitted with Damped Cable System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asad%20Naeem">Asad Naeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Nour%20Eldin"> Mohamed Nour Eldin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinkoo%20Kim"> Jinkoo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the seismic performance and life cycle cost (LCC) are evaluated of the structure retrofitted with the damped cable system (DCS). The DCS is a seismic retrofit system composed of a high-strength steel cable and pressurized viscous dampers. The analysis model of the system is first derived using various link elements in SAP2000, and fragility curves of the structure retrofitted with the DCS and viscous dampers are obtained using incremental dynamic analyses. The analysis results show that the residual displacements of the structure equipped with the DCS are smaller than those of the structure with retrofitted with only conventional viscous dampers, due to the enhanced stiffness/strength and self-centering capability of the damped cable system. The fragility analysis shows that the structure retrofitted with the DCS has the least probability of reaching the specific limit states compared to the bare structure and the structure with viscous damper. It is also observed that the initial cost of the DCS method required for the seismic retrofit is smaller than that of the structure with viscous dampers and that the LCC of the structure equipped with the DCS is smaller than that of the structure with viscous dampers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damped%20cable%20system" title="damped cable system">damped cable system</a>, <a href="https://publications.waset.org/abstracts/search?q=fragility%20curve" title=" fragility curve"> fragility curve</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20cost" title=" life cycle cost"> life cycle cost</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20retrofit" title=" seismic retrofit"> seismic retrofit</a>, <a href="https://publications.waset.org/abstracts/search?q=self-centering" title=" self-centering"> self-centering</a> </p> <a href="https://publications.waset.org/abstracts/77662/life-cycle-cost-evaluation-of-structures-retrofitted-with-damped-cable-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77662.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">551</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">1301</span> Fabrication of Cesium Iodide Columns by Rapid Heating Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chien-Wan%20Hun">Chien-Wan Hun</a>, <a href="https://publications.waset.org/abstracts/search?q=Shao-Fu%20Chang"> Shao-Fu Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Chon%20Chen"> Chien-Chon Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ker-Jer%20Huang"> Ker-Jer Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents how to use a high-efficiency process for producing cesium iodide (CsI) crystal columns by rapid heating method. In the past, the heating rate of the resistance wire heating furnace was relatively slow and excessive iodine and CsI vapors were therefore generated during heating. Because much iodine and CsI vapors are produced during heating process, the composition of CsI crystal columns is not correct. In order to enhance the heating rate, making CsI material in the heating process can quickly reach the melting point temperature. This study replaced the traditional type of external resistance heating furnace with halogen-type quartz heater, and then, CsI material can quickly reach the melting point. Eventually, CsI melt can solidify in the anodic aluminum template forming CsI crystal columns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cesium%20iodide" title="cesium iodide">cesium iodide</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20efficiency" title=" high efficiency"> high efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=vapor" title=" vapor"> vapor</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20heating" title=" rapid heating"> rapid heating</a>, <a href="https://publications.waset.org/abstracts/search?q=crystal%20column" title=" crystal column"> crystal column</a> </p> <a href="https://publications.waset.org/abstracts/69695/fabrication-of-cesium-iodide-columns-by-rapid-heating-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69695.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">373</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">1300</span> Heating Behavior of Ni-Embedded Thermoplastic Polyurethane Adhesive Film by Induction Heating</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=DuckHwan%20Bae">DuckHwan Bae</a>, <a href="https://publications.waset.org/abstracts/search?q=YongSung%20Kwon"> YongSung Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Young%20Shon"> Min Young Shon</a>, <a href="https://publications.waset.org/abstracts/search?q=SanTaek%20Oh"> SanTaek Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=GuNi%20Kim"> GuNi Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The heating behavior of nanometer and micrometer sized Nickel particle-imbedded thermoplastic polyurethane adhesive (TPU) under induction heating is examined in present study.

Two heating modes – auto and manual mode were applied to observe the role of electrical induction on heating. Temperature, electric current, and pulse pattern were experimented with grade iron γ-Al2O3 powders. Phase transformation of γ to α -Al2O3 serves as a direct indicator of internal temperature, independently on measured outside temperature. That pulsing in SPS is also able to induce internal heating due to its strong electromagnetic field when dopants are conductive metals (e.g., iron) is proofed during SPS. Density and microstructure were investigated to explain the mechanism of induction heating. In addition, the role of electric pulsing and strong electromagnetic field on internal heating (induction heating) were compared and discussed. Internal heating by iron doping within electrically nonconductive samples is able to decrease sintering temperature and save energy, furthermore it is one explanation for unique features of this material fabrication technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spark%20plasma%20sintering" title="spark plasma sintering">spark plasma sintering</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20heating" title=" induction heating"> induction heating</a>, <a href="https://publications.waset.org/abstracts/search?q=alumina" title=" alumina"> alumina</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a> </p> <a href="https://publications.waset.org/abstracts/54836/impact-of-iron-doping-on-induction-heating-during-spark-plasma-sintering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54836.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">331</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">1298</span> A Comparative Study on the Performance of Viscous and Friction Dampers under Seismic Excitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Apetsi%20K.%20Ampiah">Apetsi K.

It is for this reason that engineers have devised means of protecting buildings and thus protecting human life. Since the invention of devices such as the viscous and friction dampers, scientists/researchers have been able to incorporate these devices into buildings and other engineering structures. The viscous damper is a hydraulic device which dissipates the seismic forces by pushing fluid through an orifice, producing a damping pressure which creates a force. In the friction damper, the force is mainly resisted by converting the kinetic energy into heat by friction. Devices such as viscous and friction dampers are able to absorb almost all the earthquake energy, allowing the structure to remain undamaged (or with some amount of damage) and ready for immediate reuse (with some repair works). Comparing these two devices presents the engineer with adequate information on the merits and demerits of these devices and in which circumstances their use would be highly favorable. This paper examines the performance of both viscous and friction dampers under different ground motions. A two-storey frame installed with both devices under investigation are modeled in commercial computer software and analyzed under different ground motions. The results of the performance of the structure are then tabulated and compared. Also included in this study is the ease of installation and maintenance of these devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20damper" title="friction damper">friction damper</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic" title=" seismic"> seismic</a>, <a href="https://publications.waset.org/abstracts/search?q=slip%20load" title=" slip load"> slip load</a>, <a href="https://publications.waset.org/abstracts/search?q=viscous%20damper" title=" viscous damper"> viscous damper</a> </p> <a href="https://publications.waset.org/abstracts/103968/a-comparative-study-on-the-performance-of-viscous-and-friction-dampers-under-seismic-excitation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103968.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">168</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">1297</span> Bianchi Type- I Viscous Fluid Cosmological Models with Stiff Matter and Time Dependent Λ- Term</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajendra%20Kumar%20Dubey">Rajendra Kumar Dubey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Einstein’s field equations with variable cosmological term Λ are considered in the presence of viscous fluid for Bianchi type I space time.

This study considers a technical analysis of a combined solar water heating system with evacuated tube solar collectors for different solar coverage, ranging from 20% to 100% of the total roof area of a typical residential building located in Edmonton, Alberta, Canada. The alternative heating systems were conventional (non-condensing) and condensing tankless water heaters and condensing boilers that were coupled to solar water heating systems. The performance of the alternative heating systems was compared to a traditional heating system, consisting of a conventional boiler, applied to houses of various gross floor areas. A comparison among the annual natural gas consumption, carbon dioxide (CO<sub>2</sub>) mitigation, and emissions for the various house sizes indicated that the combined solar heating system can reduce the natural gas consumption and CO<sub>2</sub> emissions, and increase CO<sub>2</sub> mitigation for all the systems that were studied. The results suggest that solar water heating systems are potentially beneficial for residential heating system applications in terms of energy savings and CO<sub>2</sub> mitigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO2%20emissions" title="CO2 emissions">CO2 emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20mitigation" title=" CO2 mitigation"> CO2 mitigation</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20gas%20consumption" title=" natural gas consumption"> natural gas consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20water%20heating%20system" title=" solar water heating system"> solar water heating system</a> </p> <a href="https://publications.waset.org/abstracts/49148/technical-analysis-of-combined-solar-water-heating-systems-for-cold-climate-regions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49148.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">324</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">1295</span> Synthesis and Characterization of CaZrTi2O7 from Tartrate Precursor Employing Microwave Heating Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20M.%20Patil">B.

In the present work the nanocrystalline CaZrTi2O7 was synthesized from Calcium Zirconyl Titanate tartrate precursor (CZTT) employing two different heating techniques such as Conventional heating (Muffle furnace) and Microwave heating (Microwave Oven). Thermal decomposition of the CZTT precursors in air yielded nanocrystalline CaZrTi2O7 powder as the end product. The products obtained by annealing the CZTT precursor using both heating method were characterized using simultaneous TG-DTA, FTIR, XRD, SEM, TEM, NTA and thermodilatometric study. The physical characteristics such as crystallinity, morphology and particle size of the product obtained by heating the CZTT precursor at the different temperatures in a Muffle furnace and Microwave oven were found to be significantly different.

The shaking table tests of a two-story steel frame installed with the proposed damping system are carried out using five different earthquake records.

In this paper, a sample of a two-story building is simulated with the help of SAP2000 software, and the effect of a viscous damper on the performance of the structure is explained. The effect of dampers on the response of the structure is investigated. This response involves the horizontal displacement of floors. In this case, the structure is modeled once without a damper and again with a damper. In this regard, the results are presented in the form of tables and graphs. Since the seismic behavior of the structure is studied, the responses show the appropriate effect of viscous dampers in reducing the displacement of floors, and also the energy dissipation in the structure with dampers compared to structures without dampers is significant. Therefore, it is economical to use viscous dampers in areas that have a higher relative earthquake risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bending%20frame" title="bending frame">bending frame</a>, <a href="https://publications.waset.org/abstracts/search?q=displacement%20criterion" title=" displacement criterion"> displacement criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20response%20spectra" title=" dynamic response spectra"> dynamic response spectra</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake" title=" earthquake"> earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20history%20spectrum" title=" non-linear history spectrum"> non-linear history spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=SAP2000%20software" title=" SAP2000 software"> SAP2000 software</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20response" title=" structural response"> structural response</a>, <a href="https://publications.waset.org/abstracts/search?q=viscous%20damper" title=" viscous damper"> viscous damper</a> </p> <a href="https://publications.waset.org/abstracts/147515/review-and-evaluation-of-viscose-damper-on-structural-responses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147515.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">115</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">1290</span> Thermal Comfort Characteristics in an Enclosure with a Radiant Ceiling Heating and Floor Air Heating System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seung-Ho%20Yoo">Seung-Ho Yoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Ryeul%20Sohn"> Jong-Ryeul Sohn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An environmental friendly or efficient heating & cooling systems attract a great attention, due to the energy or environmental problems.

Our system is based on the circulation of a Heat transfer fluid, which is water in our case, in a closed loop under the greenhouse's roof in order to store heat all day, and then this heat will supply the greenhouse during the night. In order to evaluate our greenhouse, we made an experimental study in two identical greenhouses, where the first one is equipped with a heating system and the second (without heating) is used for control. The heating system allows the establishment of the thermal balance and determines the mass of water necessary for the process in order to ensure its functioning during the night. The results obtained showed that this solar heating system and the climatic parameters inside the experimental greenhouse were improved, and it presents a significant gain compared to a controlled greenhouse without a heating system. This research is one of the solutions that help to reduce the greenhouse effect of the planet Earth, a problem that worries the world. <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=energy%20storage" title=" energy storage"> energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=greenhouse" title=" greenhouse"> greenhouse</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a> </p> <a href="https://publications.waset.org/abstracts/167095/copper-coil-heat-exchanger-performance-for-greenhouse-heating-an-experimental-and-theoretical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167095.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">78</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">1288</span> Electromagnetic Interference Shielding Effectiveness of a Corrugated Rectangular Waveguide for a Microwave Conveyor-Belt Drier </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sang-Hyeon%20Bae">Sang-Hyeon Bae</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Yeon%20Kim"> Sung-Yeon Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Gyo%20Jeong"> Min-Gyo Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji-Hong%20Kim"> Ji-Hong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang-Sang%20Lee"> Wang-Sang Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditional heating methods such as electric ovens or steam heating are slow and not very efficient. For continuously heating the objects, a microwave conveyor-belt drier is widely used in the industrial microwave heating systems. However, there is a problem in which electromagnetic wave leaks toward outside of the heating cavity through the insertion opening. To achieve the prevention of the leakage of microwaves and improved heating characteristics, the corrugated rectangular waveguide at the entrance and exit openings of a microwave conveyor-belt drier is proposed and its electromagnetic interference (EMI) shielding effectiveness is analyzed and verified.

Mango pulp was processed by using ohmic heating under the studied suitable conditions. Physical, chemical and microbiological properties of mango pulp were studied. The results showed that processing of mango pulp by using either ohmic heating or conventional method caused a decrease in the contents of TSS, total carbohydrates, total acidity, total sugars (reducing and non-reducing sugar) and an increase in phenol content, ascorbic acid and carotenoids compared to the conventional process. The increase in electric conductivity of mango pulp during ohmic heating was due to the addition of some electrolytes (salts) to increase the ions and enhance the process. The results also indicate that mango pulp processed by ohmic heating contained more phenols, carbohydrates and vitamin C and less HMF compared to that produced by conventional one. Total pectin and its fractions had slightly reduced by ohmic heating compared to conventional method. Enzymatic activities showed a reduction in poly phenoloxidase (PPO) and polygalacturonase (PG) activity in mango pulp processed by conventional method. However, ohmic heating completely inhibited PPO and PG activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ohmic%20heating" title="ohmic heating">ohmic heating</a>, <a href="https://publications.waset.org/abstracts/search?q=mango%20pulp" title=" mango pulp"> mango pulp</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic" title=" phenolic"> phenolic</a>, <a href="https://publications.waset.org/abstracts/search?q=sarotenoids" title=" sarotenoids "> sarotenoids </a> </p> <a href="https://publications.waset.org/abstracts/7967/production-and-evaluation-of-mango-pulp-by-using-ohmic-heating-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7967.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">455</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">1283</span> Effect of Viscous Dissipation and Axial Conduction in Thermally Developing Region of the Channel Partially Filled with a Porous Material Subjected to Constant Wall Heat Flux</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D%20Bhargavi">D Bhargavi</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Sharath%20Kumar%20Reddy"> J.

Results of analytical and numerical solutions are reported for various parametric conditions to illustrate special features of the solutions. The coefficient of skin friction and rate of heat transfer are obtained and illustrated graphically. The numerical solution is shown to be in excellent agreement with the closed form analytical solution.
