heat transfer in the absorber plates of a flat-plate solar collector based on the dual-phase-lag (DPL) heat conduction model. An efficient numerical scheme involving the hybrid application of the Laplace transform and control volume methods is used to solve the linear hyperbolic heat conduction equation. This work also examines the effect of different medium parameters on the behavior of heat transfer. Results show that, while the heat-flux phase lag induces thermal waves in the medium, the temperature-gradient phase lag smoothens the thermal waves by promoting non-Fourier diffusion-like conduction into the medium. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorber%20plates" title="absorber plates">absorber plates</a>, <a href="https://publications.waset.org/abstracts/search?q=dual-phase-lag" title=" dual-phase-lag"> dual-phase-lag</a>, <a href="https://publications.waset.org/abstracts/search?q=non-Fourier" title=" non-Fourier"> non-Fourier</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20collector" title=" solar collector"> solar collector</a> </p> <a href="https://publications.waset.org/abstracts/46764/study-of-heat-transfer-in-the-absorber-plates-of-a-flat-plate-solar-collector-using-dual-phase-lag-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46764.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">391</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">668</span> Polarization Insensitive Absorber with Increased Bandwidth Using Multilayer Metamaterial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Srilaxmi%20Gangula">Srilaxmi Gangula</a>, <a href="https://publications.waset.org/abstracts/search?q=MahaLakshmi%20Vinukonda"> MahaLakshmi Vinukonda</a>, <a href="https://publications.waset.org/abstracts/search?q=Neeraj%20Rao"> Neeraj Rao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A wide band polarization insensitive metamaterial absorber with bandwidth enhancement in X and C band is proposed.

By applying relative damage concept, it is possible to conclude that the variation on the shock absorber conditions will significantly affect the load applied on the pavement.

The efficiency of Stockbridge damper depends on its location on the conductor and its resonant frequencies. When the Stockbridge damper is located on a vibration node, it becomes inefficient. Hence, the static damper should be subrogated by a dynamic one. In the present study, a proposed dynamic absorber for transmission lines is studied. Hamilton’s principle is used to derive the governing equations, then the system of ordinary differential equations is solved numerically. Parametric studies are conducted to determine how certain parameters affect the performance of the absorber. The results demonstrate that replacing the static absorber by a dynamic one enhance the absorber performance for wider range of frequencies. The results also indicate that the maximum displacement decreases as the absorber speed and the forcing frequency increase. However, this reduction in maximum displacement is accompanying with increasing in the steady state vibration displacement. It is also indicated that the energy dissipation in moving absorber covers higher range of frequencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorber%20performance" title="absorber performance">absorber performance</a>, <a href="https://publications.waset.org/abstracts/search?q=Aeolian%20vibration" title=" Aeolian vibration"> Aeolian vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamilton%E2%80%99s%20principle" title=" Hamilton’s principle"> Hamilton’s principle</a>, <a href="https://publications.waset.org/abstracts/search?q=stockbridge%20damper" title=" stockbridge damper"> stockbridge damper</a> </p> <a href="https://publications.waset.org/abstracts/66478/vibration-analysis-of-power-lines-with-moving-dampers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66478.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">267</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">664</span> Behavior of Laminated Plates under Mechanical Loading</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> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study the use of two variable refined plate theories of laminated composite plates to static response of laminated plates.

The double flow corrugated absorber solar air heater performs thermally better than the flat plate double flow and conventional flat-plate solar air heater under same operating conditions. However, the corrugated absorber leads to higher pressure drop thereby increasing pumping power. The results revealed that the energy and exergy efficiencies of double flow corrugated absorber solar air heater is much higher than conventional solar air heater with the concept involving of increase in heat transfer surface area and turbulence in air flow.

These have an application in aircrafts, railway coaches, bridges etc. because they are easy to handle, have got improved properties and the cost of their fabrication is low. But their failure can lead to catastrophic disasters. And generally, the failure of these structures is due to the combined effect of excessive stresses on it and buckling. Hence, the buckling behavior of these kinds of plates should be analyzed properly. Holes are provided either at the center or elsewhere in the laminar plates for the purpose of pipes for electric cables or other purposes. Due to the presence of holes in the plates, the stress concentration is near to the holes and the stiffness of the plates is reduced. In this study, the effect of a cut-out, its shape, different boundary conditions, length/thickness ratio, stacking sequence, and ply orientation has been studied. The analysis was carried out with laminated composite plates with circular, square and triangular cut-outs. Results show the effect of different cut-out shapes, boundary conditions, the orientation of layers and length/thickness ratio of the buckling load <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling" title="buckling">buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20plates" title=" composite plates"> composite plates</a>, <a href="https://publications.waset.org/abstracts/search?q=cut-out" title=" cut-out"> cut-out</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress "> stress </a> </p> <a href="https://publications.waset.org/abstracts/47770/buckling-analysis-of-laminated-composite-plates-with-central-holes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47770.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">330</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">660</span> The Effect of Global Solar Radiation on the Thermal and Thermohydraulic Performance of Double Flow Corrugated Absorber Solar Air Heater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suresh%20Prasad%20Sharma">Suresh Prasad Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Som%20Nath%20Saha"> Som Nath Saha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with the effect of Global Solar Radiation (GSR) on the performance of double flow solar air heater having corrugated plate as an absorber.

It is found that the double flow arrangement effectively increases the air temperature rise and efficiencies in comparison to a conventional collector. However, corrugated absorber is more superior to that of flat plate double flow solar air heater. The results indicate that increasing the solar radiation leads to achieve higher air temperature rise and efficiencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrugated%20absorber" title="corrugated absorber">corrugated absorber</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20flow" title=" double flow"> double flow</a>, <a href="https://publications.waset.org/abstracts/search?q=flat%20plate" title=" flat plate"> flat plate</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20air%20heater" title=" solar air heater"> solar air heater</a> </p> <a href="https://publications.waset.org/abstracts/75539/the-effect-of-global-solar-radiation-on-the-thermal-and-thermohydraulic-performance-of-double-flow-corrugated-absorber-solar-air-heater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75539.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">285</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">659</span> Approaches to Vibration Analysis of Thick Plates Subjected to Different Supports, Loadings and Boundary Conditions: A Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fazl%20E.%20Ahad">Fazl E.

The strategy is most effective for a primary plant subjected to a single frequency excitation. For continuous systems, notable advances in vibration absorption in the multi-frequency system were made. However, the efficacy of the VA strategy for systems under multi-frequency excitation is not well understood. For example, for an N degrees-of-freedom (DOF) primary-absorber system, there are N 'peak' frequencies of large amplitude vibration per every new excitation frequency. In general, the usable range for vibration absorption can be greatly reduced as a result. Frequency modulated harmonic excitation is a commonly seen multi-frequency excitation example: f(t) = cos(ϖ(t)t) where ϖ(t)=ω(1+α sin⁡(δt)). It is known that f(t) has a series expansion given by the Bessel function of the first kind, which implies an infinity of forcing frequencies in the frequency modulated harmonic excitation. For an SDOF system of natural frequency ωₙ subjected to f(t), it can be shown that amplitude peaks emerge at ω₍ₚ,ₖ₎=(ωₙ ± 2kδ)/(α ∓ 1),k∈Z; i.e., there is an infinity of resonant frequencies ω₍ₚ,ₖ₎, k∈Z, making the use of VA strategy ineffective. In this work, we propose an absorber frequency placement strategy for SDOF vibration systems subjected to frequency-modulated excitation. An SDOF linear mass-spring system coupled to lateral absorber systems is used to demonstrate the ideas. Although the mechanical components are linear, the governing equations for the coupled system are nonlinear. We show using N identical absorbers, for N ≫ 1, that (a) there is a cluster of N+1 natural frequencies around every natural absorber frequency, and (b) the absorber frequencies can be moved away from the plant's resonance frequency (ω₀) as N increases. Moreover, we also show the bandwidth of the VA performance increases with N. The derivations of the clustering and bandwidth widening effect will be given, and the superiority of the proposed strategy will be demonstrated via numerical experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bessel%20function" title="Bessel function">Bessel function</a>, <a href="https://publications.waset.org/abstracts/search?q=bandwidth" title=" bandwidth"> bandwidth</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20modulated%20excitation" title=" frequency modulated excitation"> frequency modulated excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20absorber" title=" vibration absorber"> vibration absorber</a> </p> <a href="https://publications.waset.org/abstracts/132303/vibration-absorption-strategy-for-multi-frequency-excitation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132303.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">157</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">653</span> Interval Type-2 Fuzzy Vibration Control of an ERF Embedded Smart Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chih-Jer%20Lin">Chih-Jer Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Ying%20Lee"> Chun-Ying Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying%20Liu"> Ying Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiang-Ho%20Cheng"> Chiang-Ho Cheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this article is to present the semi-active vibration control using an electro-rheological fluid embedded sandwich structure for a cantilever beam. ER fluid is a smart material, which cause the suspended particles polarize and connect each other to form chain. The stiffness and damping coefficients of the ER fluid can be changed in 10 micro seconds; therefore, ERF is suitable to become the material embedded in the tunable vibration absorber to become a smart absorber. For the ERF smart material embedded structure, the fuzzy control law depends on the experimental expert database and the proposed self-tuning strategy. The electric field is controlled by a CRIO embedded system to implement the real application. This study investigates the different performances using the Type-1 fuzzy and interval Type-2 fuzzy controllers. The Interval type-2 fuzzy control is used to improve the modeling uncertainties for this ERF embedded shock absorber. The self-tuning vibration controllers using Type-1 and Interval Type-2 fuzzy law are implemented to the shock absorber system. Based on the resulting performance, Internal Type-2 fuzzy is better than the traditional Type-1 fuzzy control for this vibration control system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electro-rheological%20fluid" title="electro-rheological fluid">electro-rheological fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-active%20vibration%20control" title=" semi-active vibration control"> semi-active vibration control</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20absorber" title=" shock absorber"> shock absorber</a>, <a href="https://publications.waset.org/abstracts/search?q=type%202%20fuzzy%20control" title=" type 2 fuzzy control "> type 2 fuzzy control </a> </p> <a href="https://publications.waset.org/abstracts/7630/interval-type-2-fuzzy-vibration-control-of-an-erf-embedded-smart-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7630.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">447</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">652</span> Failure Mechanism of Slip-Critical Connections on Curved Surface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bae%20Doobyong">Bae Doobyong</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoo%20Jaejun"> Yoo Jaejun</a>, <a href="https://publications.waset.org/abstracts/search?q=Park%20Ilgyu"> Park Ilgyu</a>, <a href="https://publications.waset.org/abstracts/search?q=Choi%20Seowon"> Choi Seowon</a>, <a href="https://publications.waset.org/abstracts/search?q=Oh%20Chang%20Kook"> Oh Chang Kook</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Variation of slip coefficient in slip-critical connections of curved plates.

A double-layered absorber consisting of a 32 nm thick aluminum (Al) metallic layer, located on a glass medium (SiO2) of 1 mm thickness, was fabricated and used to design a fine-tuned absorber through a theoretical and finite element modeling process. The results indicate that the proposed low-cost, double-layered absorber can be tuned based on the metal layer sheet resistance and the thickness of various glass media taking advantage of the diversity of the absorption of the metal films in the desired THz domain (6 to 10 THz). It was found that the composite absorber could absorb up to 86% (a percentage exceeding the 50%, previously shown to be the highest achievable when using single thin metal layer) and reflect less than 1% of the incident THz power. This approach will enable monitoring of the transmission coefficient (THz transmission ‘’fingerprint’’) of the biosample with high accuracy, while also making the proposed double-layered absorber a good candidate for a microbolometer pixel’s active element. Based on the aforementioned promising results, a more sophisticated and effective double-layered absorber is under development. The glass medium has been substituted by diluted poly-si and the results were twofold: An absorption factor of 96% was reached and high TCR properties acquired. In addition, a generalization of these results and properties over the active frequency spectrum was achieved. Specifically, through the development of a theoretical equation having as input any arbitrary frequency in the IR spectrum (0.3 to 405.4 THz) and as output the appropriate thickness of the poly-si medium, the double-layered absorber retains the ability to absorb the 96% and reflects less than 1% of the incident power. As a result, through that post-optimization process and the spread spectrum frequency adjustment, the microbolometer detector efficiency could be further improved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-imaging" title="bio-imaging">bio-imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=fine-tuned%20absorber" title=" fine-tuned absorber"> fine-tuned absorber</a>, <a href="https://publications.waset.org/abstracts/search?q=fingerprint" title=" fingerprint"> fingerprint</a>, <a href="https://publications.waset.org/abstracts/search?q=microbolometer" title=" microbolometer"> microbolometer</a> </p> <a href="https://publications.waset.org/abstracts/43851/optimizing-detection-methods-for-thz-bio-imaging-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43851.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">348</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">648</span> Thermohydraulic Performance of Double Flow Solar Air Heater with Corrugated Absorber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20P.%20Sharma">S.

A mathematical model of double flow solar air heater has been presented, and a computer program in C<sup>++</sup> language is developed to estimate the outlet temperature of air for the evaluation of thermal and thermohydraulic efficiency by solving the governing equations numerically using relevant correlations for heat transfer coefficients. The results obtained from the mathematical model is compared with the available experimental results and it is found to be reasonably good. The results show that the double flow solar air heaters have higher efficiency than conventional solar air heater, although the double flow corrugated absorber is superior to that of flat plate double flow solar air heater. It is also observed that the thermal efficiency increases with increase in mass flow rate; however, thermohydraulic efficiency increases with increase in mass flow rate up to a certain limit, attains the maximum value, then thereafter decreases sharply. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrugated%20absorber" title="corrugated absorber">corrugated absorber</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20flow" title=" double flow"> double flow</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20air%20heater" title=" solar air heater"> solar air heater</a>, <a href="https://publications.waset.org/abstracts/search?q=thermos-hydraulic%20efficiency" title=" thermos-hydraulic efficiency"> thermos-hydraulic efficiency</a> </p> <a href="https://publications.waset.org/abstracts/69780/thermohydraulic-performance-of-double-flow-solar-air-heater-with-corrugated-absorber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69780.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">314</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">647</span> Study on Buckling and Yielding Behaviors of Low Yield Point Steel Plates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Boyajian">David Boyajian</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadeh%20Zirakian"> Tadeh Zirakian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stability and performance of steel plates are characterized by geometrical buckling and material yielding. In this paper, the geometrical buckling and material yielding behaviors of low yield point (LYP) steel plates are studied from the point of view of their application in steel plate shear wall (SPSW) systems. Use of LYP steel facilitates the design and application of web plates with improved buckling and energy absorption capacities in SPSW systems. LYP steel infill plates may yield first and then undergo inelastic buckling. Hence, accurate determination of the limiting plate thickness corresponding to simultaneous buckling and yielding can be effective in seismic design of such lateral force-resisting and energy dissipating systems. The limiting thicknesses of plates with different loading and support conditions are determined theoretically and verified through detailed numerical simulations. Effects of use of LYP steel and plate aspect ratio parameter on the limiting plate thickness are investigated as well. In addition, detailed studies are performed on determination of the limiting web-plate thickness in code-designed SPSWs. Some practical recommendations are accordingly provided for efficient seismic design of SPSW systems with LYP steel infill plates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling" title="buckling">buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20yield%20point%20steel" title=" low yield point steel"> low yield point steel</a>, <a href="https://publications.waset.org/abstracts/search?q=plates" title=" plates"> plates</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20plate%20shear%20walls" title=" steel plate shear walls"> steel plate shear walls</a>, <a href="https://publications.waset.org/abstracts/search?q=yielding" title=" yielding"> yielding</a> </p> <a href="https://publications.waset.org/abstracts/50611/study-on-buckling-and-yielding-behaviors-of-low-yield-point-steel-plates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50611.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">401</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">646</span> A Closed-Form Solution and Comparison for a One-Dimensional Orthorhombic Quasicrystal and Crystal Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arpit%20Bhardwaj">Arpit Bhardwaj</a>, <a href="https://publications.waset.org/abstracts/search?q=Koushik%20Roy"> Koushik Roy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work includes derivation of the exact-closed form solution for simply supported quasicrystal and crystal plates by using propagator matrix method under surface loading and free vibration.

There are various types of solar collectors, and parabolic trough collectors (PTCs) are common among these types. In PTCs, a mirror is used to direct the incident radiation on an absorber tube to utilize the heat in power generation. In this work, a PTC covered with a glass tube is presented and analyzed. Results showed that temperatures of 510℃ for steam can be reached for certain parameters. The work also showed the viability of using Benzene as the working fluid in the absorber tube. Also, some analysis regarding changing the absorber’s tube diameter and the efficiency of the solar collector was demonstrated in this work. The effect of changing the heat transfer correlations for the convection phenomena of the working fluid was illustrated. In fact, two heat transfer correlations, the Dittus-Boelter and Gnielinski correlations, were used, and the outcomes showed a resemblance in the results for the maximum attainable temperature in the working fluid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorber%20tube" title="absorber tube">absorber tube</a>, <a href="https://publications.waset.org/abstracts/search?q=glass%20tube" title=" glass tube"> glass tube</a>, <a href="https://publications.waset.org/abstracts/search?q=incident%20radiation" title=" incident radiation"> incident radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=parabolic%20trough%20collector" title=" parabolic trough collector"> parabolic trough collector</a> </p> <a href="https://publications.waset.org/abstracts/194511/analysis-on-heat-transfer-in-solar-parabolic-trough-collectors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194511.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">10</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">643</span> Solar Still Absorber Plate Modification and Exergy Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dudul%20Das">Dudul Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Pankaj%20Kalita"> Pankaj Kalita</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangeeta%20Borah"> Sangeeta Borah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Freshwater availability in the world is as low as 1% of total water available and in many geographical locations dissolved fluoride and arsenic are serious problem. In India availability of freshwater will be stressed by 2025, so the availability saline water from sea is a hope for the people of Indian sub-continent, but saline water is not drinkable it need to be processed, which again require a huge amount of energy. So the most easy and handy option in such situation for all those problems is solar still, this investigation presents various scopes for improvement of its efficiency. Experiments showed that by increasing the absorber plate area through better design can increase the distillate output by two fold and by using jute wicks in the modified absorber plate increases the output up to three times that of conventional solar still available in the Department of Energy, Tezpur University. The experiment is carried out at constant water depth of 8.5 cm and glass cover inclination of 27o facing South. The exergy analysis carried out clearly resulted that with the use of jute wick and baffle plated basin the efficiency achieved more than the simple baffle plated basin. The Instantaneous exergy without jute wick ranges from 2.5% to 4.5% while using jute it ranges from 1.5% to 5.15%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluoride" title="fluoride">fluoride</a>, <a href="https://publications.waset.org/abstracts/search?q=absorber%20plate" title=" absorber plate"> absorber plate</a>, <a href="https://publications.waset.org/abstracts/search?q=jute%20wick" title=" jute wick"> jute wick</a>, <a href="https://publications.waset.org/abstracts/search?q=instantaneous%20exergy" title=" instantaneous exergy"> instantaneous exergy</a> </p> <a href="https://publications.waset.org/abstracts/25234/solar-still-absorber-plate-modification-and-exergy-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25234.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">642</span> A Model-Based Approach for Energy Performance Assessment of a Spherical Stationary Reflector/Tracking Absorber Solar Concentrator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rosa%20Christodoulaki">Rosa Christodoulaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Irene%20Koronaki"> Irene Koronaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Panagiotis%20Tsekouras"> Panagiotis Tsekouras</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to analyze the energy performance of a spherical Stationary Reflector / Tracking Absorber (SRTA) solar concentrator. This type of collector consists of a segment of a spherical mirror placed in a stationary position facing the sun and a cylindrical absorber that tracks the sun by a simple pivoting motion about the center of curvature of the reflector. The energy analysis is performed through the development of a dynamic simulation model in TRNSYS software that calculates the annual heat production and the efficiency of the SRTA solar concentrator. The effect of solar concentrator design features and characteristics, such the reflector material, the reflector diameter, the receiver type, the solar radiation level and the concentration ratio, are discussed in details. Moreover, the energy performance curve of the SRTA solar concentrator, for various temperature differences between the mean fluid temperature and the ambient temperature and radiation intensities is drawn. The results are shown in diagrams, visualizing the effect of solar, optical and thermal parameters to the overall performance of the SRTA solar concentrator throughout the year.
