In the accident and thus in the experiment, the ECC water was injected not only into the cold legs but into the upper plenum. Overall transients during the experiment such as pressures and fluid temperatures are simulated well by the code. The cold-leg fluid temperatures are shown to decrease if the upper plenum injection system is connected to the cold leg. It is found that the cold-leg fluid temperatures also decrease if the upper-plenum injection is not used and the cold-leg injection alone is actuated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SGTR" title="SGTR">SGTR</a>, <a href="https://publications.waset.org/abstracts/search?q=LSTF" title=" LSTF"> LSTF</a>, <a href="https://publications.waset.org/abstracts/search?q=RELAP5" title=" RELAP5"> RELAP5</a>, <a href="https://publications.waset.org/abstracts/search?q=ECCS" title=" ECCS"> ECCS</a> </p> <a href="https://publications.waset.org/abstracts/30723/effects-of-eccs-on-the-cold-leg-fluid-temperature-during-sgtr-accidents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30723.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">666</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">2201</span> Modeling of Leaks Effects on Transient Dispersed Bubbly Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohand%20Kessal">Mohand Kessal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Boucetta"> Rachid Boucetta</a>, <a href="https://publications.waset.org/abstracts/search?q=Mourad%20Tikobaini"> Mourad Tikobaini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Zamoum"> Mohammed Zamoum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leakage problem of two-component fluids flow is modeled for a transient one-dimensional homogeneous bubbly flow and developed by taking into account the effect of a leak located at the middle point of the pipeline.

The impact of these systems on the grid has not been studied or analyzed. These systems can cause many technical problems such as reverse power flows and voltage rises in distribution feeders, and real and reactive power transients that affect the operation of the transmission system. To fully understand and address these problems, extensive research, simulation, and case studies are required. To this end, this paper studies the cloud shadow effect on the power generation of a ground mounted PV system installed at the test field of the Renewable Energy Center at the Applied Science University. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title="photovoltaic">photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20effect" title=" cloud effect"> cloud effect</a>, <a href="https://publications.waset.org/abstracts/search?q=MPPT" title=" MPPT"> MPPT</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20transients" title=" power transients"> power transients</a> </p> <a href="https://publications.waset.org/abstracts/37102/cloud-effect-on-power-generation-of-grid-connected-small-pv-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37102.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">599</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">2199</span> Pulsed Laser Single Event Transients in 0.18 μM Partially-Depleted Silicon-On-Insulator Device</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=MeiBo">MeiBo</a>, <a href="https://publications.waset.org/abstracts/search?q=ZhaoXing"> ZhaoXing</a>, <a href="https://publications.waset.org/abstracts/search?q=LuoLei"> LuoLei</a>, <a href="https://publications.waset.org/abstracts/search?q=YuQingkui"> YuQingkui</a>, <a href="https://publications.waset.org/abstracts/search?q=TangMin"> TangMin</a>, <a href="https://publications.waset.org/abstracts/search?q=HanZhengsheng"> HanZhengsheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Single Event Transients (SETs) were investigated on 0.18μm PDSOI transistors and 100 series CMOS inverter chain using pulse laser. The effect of different laser energy and device bias for waveform on SET was characterized experimentally, as well as the generation and propagation of SET in inverter chain. In this paper, the effects of struck transistors type and struck locations on SETs were investigated. The results showed that when irradiate NMOSFETs from 100th to 2nd stages, the SET pulse width measured at the output terminal increased from 287.4 ps to 472.9 ps; and when irradiate PMOSFETs from 99th to 1st stages, the SET pulse width increased from 287.4 ps to 472.9 ps. When struck locations were close to the output of the chain, the SET pulse was narrow; however, when struck nodes were close to the input, the SET pulse was broadening. SET pulses were progressively broadened up when propagating along inverter chains. The SET pulse broadening is independent of the type of struck transistors. Through analysis, history effect induced threshold voltage hysteresis in PDSOI is the reason of pulse broadening. The positive pulse observed by oscilloscope, contrary to the expected results, is because of charging and discharging of capacitor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=single%20event%20transients" title="single event transients">single event transients</a>, <a href="https://publications.waset.org/abstracts/search?q=pulse%20laser" title=" pulse laser"> pulse laser</a>, <a href="https://publications.waset.org/abstracts/search?q=partially-depleted%20silicon-on-insulator" title=" partially-depleted silicon-on-insulator"> partially-depleted silicon-on-insulator</a>, <a href="https://publications.waset.org/abstracts/search?q=propagation-induced%20pulse%20broadening%20effect" title=" propagation-induced pulse broadening effect"> propagation-induced pulse broadening effect</a> </p> <a href="https://publications.waset.org/abstracts/34850/pulsed-laser-single-event-transients-in-018-mm-partially-depleted-silicon-on-insulator-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34850.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">412</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">2198</span> An Object-Oriented Modelica Model of the Water Level Swell during Depressurization of the Reactor Pressure Vessel of the Boiling Water Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafal%20Bryk">Rafal Bryk</a>, <a href="https://publications.waset.org/abstracts/search?q=Holger%20Schmidt"> Holger Schmidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Mull"> Thomas Mull</a>, <a href="https://publications.waset.org/abstracts/search?q=Ingo%20Ganzmann"> Ingo Ganzmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Oliver%20Herbst"> Oliver Herbst </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prediction of the two-phase water mixture level during fast depressurization of the Reactor Pressure Vessel (RPV) resulting from an accident scenario is an important issue from the view point of the reactor safety. Since the level swell may influence the behavior of some passive safety systems, it has been recognized that an assumption which at the beginning may be considered as a conservative one, not necessary leads to a conservative result. This paper discusses outcomes obtained during simulations of the water dynamics and heat transfer during sudden depressurization of a vessel filled up to a certain level with liquid water under saturation conditions and with the rest of the vessel occupied by saturated steam. In case of the pressure decrease e.g. due to the main steam line break, the liquid water evaporates abruptly, being a reason thereby, of strong transients in the vessel. These transients and the sudden emergence of void in the region occupied at the beginning by liquid, cause elevation of the two-phase mixture. In this work, several models calculating the water collapse and swell levels are presented and validated against experimental data. Each of the models uses different approach to calculate void fraction. The object-oriented models were developed with the Modelica modelling language and the OpenModelica environment. The models represent the RPV of the Integral Test Facility Karlstein (INKA) – a dedicated test rig for simulation of KERENA – a new Boiling Water Reactor design of Framatome. The models are based on dynamic mass and energy equations. They are divided into several dynamic volumes in each of which, the fluid may be single-phase liquid, steam or a two-phase mixture. The heat transfer between the wall of the vessel and the fluid is taken into account. Additional heat flow rate may be applied to the first volume of the vessel in order to simulate the decay heat of the reactor core in a similar manner as it is simulated at INKA. The comparison of the simulations results against the reference data shows a good agreement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boiling%20water%20reactor" title="boiling water reactor">boiling water reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20swell" title=" level swell"> level swell</a>, <a href="https://publications.waset.org/abstracts/search?q=Modelica" title=" Modelica"> Modelica</a>, <a href="https://publications.waset.org/abstracts/search?q=RPV%20depressurization" title=" RPV depressurization"> RPV depressurization</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal-hydraulics" title=" thermal-hydraulics"> thermal-hydraulics</a> </p> <a href="https://publications.waset.org/abstracts/88936/an-object-oriented-modelica-model-of-the-water-level-swell-during-depressurization-of-the-reactor-pressure-vessel-of-the-boiling-water-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88936.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">210</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">2197</span> Numerical Simulation of Fluid Structure Interaction Using Two-Way Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Laidaoui">Samira Laidaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Djermane"> Mohammed Djermane</a>, <a href="https://publications.waset.org/abstracts/search?q=Nazihe%20Terfaya"> Nazihe Terfaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The fluid-structure coupling is a natural phenomenon which reflects the effects of two continuums: fluid and structure of different types in the reciprocal action on each other, involving knowledge of elasticity and fluid mechanics. The solution for such problems is based on the relations of continuum mechanics and is mostly solved with numerical methods. It is a computational challenge to solve such problems because of the complex geometries, intricate physics of fluids, and complicated fluid-structure interactions. The way in which the interaction between fluid and solid is described gives the largest opportunity for reducing the computational effort. In this paper, a problem of fluid structure interaction is investigated with two-way coupling method. The formulation Arbitrary Lagrangian-Eulerian (ALE) was used, by considering a dynamic grid, where the solid is described by a Lagrangian formulation and the fluid by a Eulerian formulation.

These coefficients are used as a power system transient stability measurement. In this paper, a crow search optimization algorithm is presented and implemented to study the power system stability during transients. The algorithm makes use of the machine responses to perform the stability study in time domain. The problem is formulated as a dynamic estimation problem. An objective function that minimizes the error square in the estimated coefficients is designed. The method is tested using practical system with different study cases. Results are reported and a thorough discussion is presented. The study illustrates that the proposed method can estimate the stability coefficients for the critical stable cases where other methods may fail. The tests proved that the proposed tool is an accurate and reliable tool for estimating the machine coefficients for assessment of power system stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=estimation" title=" estimation"> estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=synchronous" title=" synchronous"> synchronous</a>, <a href="https://publications.waset.org/abstracts/search?q=machine" title=" machine"> machine</a>, <a href="https://publications.waset.org/abstracts/search?q=crow%20search" title=" crow search"> crow search</a> </p> <a href="https://publications.waset.org/abstracts/110946/estimation-of-synchronous-machine-synchronizing-and-damping-torque-coefficients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110946.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">140</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">2195</span> A Procedure for Post-Earthquake Damage Estimation Based on Detection of High-Frequency Transients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aleksandar%20Zhelyazkov">Aleksandar Zhelyazkov</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniele%20Zonta"> Daniele Zonta</a>, <a href="https://publications.waset.org/abstracts/search?q=Helmut%20Wenzel"> Helmut Wenzel</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Furtner"> Peter Furtner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current research structural health monitoring is considered for addressing the critical issue of post-earthquake damage detection. A non-standard approach for damage detection via acoustic emission is presented - acoustic emissions are monitored in the low frequency range (up to 120 Hz). Such emissions are termed high-frequency transients. Further a damage indicator defined as the Time-Ratio Damage Indicator is introduced. The indicator relies on time-instance measurements of damage initiation and deformation peaks. Based on the time-instance measurements a procedure for estimation of the maximum drift ratio is proposed. Monitoring data is used from a shaking-table test of a full-scale reinforced concrete bridge pier. Damage of the experimental column is successfully detected and the proposed damage indicator is calculated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20emission" title="acoustic emission">acoustic emission</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20detection" title=" damage detection"> damage detection</a>, <a href="https://publications.waset.org/abstracts/search?q=shaking%20table%20test" title=" shaking table test"> shaking table test</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20health%20monitoring" title=" structural health monitoring"> structural health monitoring</a> </p> <a href="https://publications.waset.org/abstracts/99423/a-procedure-for-post-earthquake-damage-estimation-based-on-detection-of-high-frequency-transients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99423.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">231</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">2194</span> Modeling of Transformer Winding for Transients: Frequency-Dependent Proximity and Skin Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yazid%20%20Alkraimeen">Yazid Alkraimeen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Precise prediction of dielectric stresses and high voltages of power transformers require the accurate calculation of frequency-dependent parameters. A lack of accuracy can result in severe damages to transformer windings. Transient conditions is stuided by digital computers, which require the implementation of accurate models. This paper analyzes the computation of frequency-dependent skin and proximity losses included in the transformer winding model, using analytical equations and Finite Element Method (FEM). A modified formula to calculate the proximity and the skin losses is presented. The results of the frequency-dependent parameter calculations are verified using the Finite Element Method. The time-domain transient voltages are obtained using Numerical Inverse Laplace Transform. The results show that the classical formula for proximity losses is overestimating the transient voltages when compared with the results obtained from the modified method on a simple transformer geometry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fast%20front%20transients" title="fast front transients">fast front transients</a>, <a href="https://publications.waset.org/abstracts/search?q=proximity%20losses" title=" proximity losses"> proximity losses</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer%20winding%20modeling" title=" transformer winding modeling"> transformer winding modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20losses" title=" skin losses"> skin losses</a> </p> <a href="https://publications.waset.org/abstracts/118676/modeling-of-transformer-winding-for-transients-frequency-dependent-proximity-and-skin-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118676.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">139</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">2193</span> Herschel-Bulkley Fluid Flow through Narrow Tubes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santhosh%20Nallapu">Santhosh Nallapu</a>, <a href="https://publications.waset.org/abstracts/search?q=G.%20Radhakrishnamacharya"> G.

It has been observed that the effective viscosity and mean hematocrit increase with yield stress, power-law index, hematocrit and tube radius.

This phenomenon of distortion, which is superimposed on the distortion by skin effect, is due to the dissipation of energy by injection of space charges around the conductor, this process with place as soon as the instantaneous voltage exceeds the threshold voltage of the corona effect conductors. This paper presents a mathematical model to determine the corona inception voltage, the critical electric field and the corona radius, to predict the capacitive changes at conductor of transmission line due to corona. This model has been incorporated into the Alternative Transients Program version of the Electromagnetic Transients Program (ATP/EMTP) as a user defined component, using the MODELS interface with NORTON TYPE94 of this program and using the foreign subroutine. For obtained the displacement of corona charge hell, dichotomy mathematical method is used for this computation. The present corona model can be used for computing of distortion and attenuation of transient overvoltage waves being propagated in a transmission line of the very high voltage electric power. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20voltage" title="high voltage">high voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=corona" title=" corona"> corona</a>, <a href="https://publications.waset.org/abstracts/search?q=Type94%20NORTON" title=" Type94 NORTON"> Type94 NORTON</a>, <a href="https://publications.waset.org/abstracts/search?q=dichotomy" title=" dichotomy"> dichotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=ATP%2FEMTP" title=" ATP/EMTP"> ATP/EMTP</a>, <a href="https://publications.waset.org/abstracts/search?q=MODELS" title=" MODELS"> MODELS</a>, <a href="https://publications.waset.org/abstracts/search?q=distortion" title=" distortion"> distortion</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20model" title=" foreign model"> foreign model</a> </p> <a href="https://publications.waset.org/abstracts/13251/modeling-of-surge-corona-using-type94-in-overhead-power-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13251.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">625</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">2191</span> Soret-Driven Convection in a Binary Fluid with Coriolis Force</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20H.%20Z.%20Abidin">N.

The performance of the product needs to be considered under both structural and fluid loads. Examples include ducts and valves where structural behavior affects fluid motion and vice versa. Simulation of fluid-structure interaction involves modeling interaction between moving components and the fluid flow. In these scenarios, it is difficult to calculate the damping provided by fluid flow because of dynamic motions of components and the transient nature of the flow. Abaqus Explicit offers general capabilities for modeling fluid-structure interaction with the Coupled Eulerian-Lagrangian (CEL) method. The Coupled Eulerian-Lagrangian technique has been used to simulate fluid spillage through fuel valves during dynamic closure events. The technique to simulate pressure drops across Eulerian domains has been developed using stagnation pressure. Also, the fluid flow is calculated considering material flow through elements at the outlet section of the valves. The methodology has been verified on Eaton products and shows a good correlation with the test results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Coupled%20Eulerian-Lagrangian%20Technique" title="Coupled Eulerian-Lagrangian Technique">Coupled Eulerian-Lagrangian Technique</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20structure%20interaction" title=" fluid structure interaction"> fluid structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=spillage%20prediction" title=" spillage prediction"> spillage prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=stagnation%20pressure" title=" stagnation pressure"> stagnation pressure</a> </p> <a href="https://publications.waset.org/abstracts/56823/spillage-prediction-using-fluid-structure-interaction-simulation-with-coupled-eulerian-lagrangian-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56823.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">379</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">2186</span> Magnetohydrodynamic Couette Flow of Fractional Burger’s Fluid in an Annulus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sani%20Isa">Sani Isa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Musa"> Ali Musa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Burgers’ fluid with a fractional derivatives model in an annulus was analyzed.

The damping force could be estimated through computational analysis using finite element and computational fluid dynamics analysis. The double-ended damper operates without changing the total volume of fluid. In this paper, damping force of double ended damper under different magnetic field is computed. Initially, the magneto-statics analysis carried out to evaluate the magnetic flux density across the fluid flow gap. The respective change in the rheology of the MR fluid is computed by using the experimentally fitted polynomial equation of shear stress versus magnetic field plot of MR fluid. The obtained values are substituted in the Herschel Buckley model to express the non-Newtonian behavior of MR fluid. Later, using computational fluid dynamic (CFD) analysis damping characteristics in terms of force versus velocity and force versus displacement for the respective magnetic field is estimated. The purpose of the present approach is to characterize the preliminary designed MR damper before fabricating. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MR%20fluid" title="MR fluid">MR fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20ended%20MR%20damper" title=" double ended MR damper"> double ended MR damper</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=FEA" title=" FEA "> FEA </a> </p> <a href="https://publications.waset.org/abstracts/98450/estimation-of-damping-force-of-double-ended-shear-mode-magnetorheological-damper-using-computational-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98450.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">180</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">2182</span> Comparison Analysis of CFD Turbulence Fluid Numerical Study for Quick Coupling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=JoonHo%20Lee">JoonHo Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=KyoJin%20An"> KyoJin An</a>, <a href="https://publications.waset.org/abstracts/search?q=JunSu%20Kim"> JunSu Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Chul%20Park"> Young-Chul Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the fluid flow characteristics and performance numerical study through CFD model of the Non-split quick coupling for flow control in hydraulic system equipment for the aerospace business group focused to predict.

The present study was conducted on follicular fluid and serum samples obtained from 708 buffaloes. Samples were examined for estradiol, progesterone, and cholesterol concentrations in relation to seasonal changes, ovarian follicular size, and stage of estrous cycle. The obtained results revealed that follicular fluid and serum levels of estradiol, progesterone, and cholesterol were significantly lower during summer and autumn when compared to winter and spring seasons. With the increase in follicular size, the follicular fluid levels of progesterone and cholesterol were significantly decreased, while estradiol levels were significantly increased. Estradiol and progesterone levels were significantly higher in follicular fluid than blood, while cholesterol was significantly lower in follicular fluid than serum. In conclusion, the current study threw a light on the hormonal changes in the follicular fluid and blood under the effect of heat stress which could be related to the low fertility of buffalo in the summer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buffalo" title="buffalo">buffalo</a>, <a href="https://publications.waset.org/abstracts/search?q=follicular%20fluid" title=" follicular fluid"> follicular fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=folliculogenesis" title=" folliculogenesis"> folliculogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonal%20changes" title=" seasonal changes"> seasonal changes</a>, <a href="https://publications.waset.org/abstracts/search?q=steroids" title=" steroids"> steroids</a> </p> <a href="https://publications.waset.org/abstracts/37224/seasonal-heat-stress-effect-on-cholesterol-estradiol-and-progesterone-during-follicular-development-in-egyptian-buffalo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37224.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">510</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">2179</span> Hydrodynamic Analysis with Heat Transfer in Solid Gas Fluidized Bed Reactor for Solar Thermal Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sam%20Rasoulzadeh">Sam Rasoulzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Atefeh%20Mousavi"> Atefeh Mousavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fluidized bed reactors are known as highly exothermic and endothermic according to uniformity in temperature as a safe and effective mean for catalytic reactors. In these reactors, a wide range of catalyst particles can be used and by using a continuous operation proceed to produce in succession. Providing optimal conditions for the operation of these types of reactors will prevent the exorbitant costs necessary to carry out laboratory work. In this regard, a hydrodynamic analysis was carried out with heat transfer in the solid-gas fluidized bed reactor for solar thermal applications. The results showed that in the fluid flow the input of the reactor has a lower temperature than the outlet, and when the fluid is passing from the reactor, the heat transfer happens between cylinder and solar panel and fluid. It increases the fluid temperature in the outlet pump and also the kinetic energy of the fluid has been raised in the outlet areas. <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=solar%20reactor" title=" solar reactor"> solar reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidized%20bed%20reactor" title=" fluidized bed reactor"> fluidized bed reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a> </p> <a href="https://publications.waset.org/abstracts/100498/hydrodynamic-analysis-with-heat-transfer-in-solid-gas-fluidized-bed-reactor-for-solar-thermal-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100498.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">179</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">2178</span> Effect of Channel Variation of Two-Dimensional Water Tunnel to Study Fluid Dynamics Phenomenon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizka%20Yunita">Rizka Yunita</a>, <a href="https://publications.waset.org/abstracts/search?q=Mas%20Aji%20Rizki%20Wijayanto"> Mas Aji Rizki Wijayanto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computational fluid dynamics (CFD) is the solution to explain how fluid dynamics behavior.

The horizontal water tunnel we used, divided into three parts, expansion area, parallel area that used to test the data, and contraction area. The width of channel is the boundary of parallel area with the originally width of 7.2 cm, and the variation of channel width we observed is about 1 cm and its times. To compute the velocity, vortex shedding, and other physical parameters of fluid, we used the cyclinder circular as an obstacle to create a von Karman vortex in fluid and analyzed that phenomenon by using Particle Imaging Velocimetry (PIV) method and comparing Reynolds number and Strouhal number from the visualization we got.

For respective porous channels, expressions for velocity vectors, microrotations, stresses (shear and couple) are obtained analytically. Continuity of velocities, continuities of micro rotations and continuity of stresses are used at the porous interfaces; conditions of no-slip and no spin are applied at the impervious boundaries of the composite channel.

It is investigated by using two-way Fluid-Structure Interaction (FSI) in a flexible tank by Coupling between the Transient Structural (Mechanical) and Fluid Flow (Fluent) in ANSYS-Workbench Student version. The Arbitrary Lagrangian-Eulerian (ALE) formulation is adopted to solve with the finite volume method, the Navier-Stokes equations in two phases in a moving domain. The Volume of Fluid (VOF) method is applied to track the free surface. However, the equations of the dynamics of the structure are solved with the finite element method assuming a linear elastic behavior. To conclude, the Fluid-Structure Interaction (IFS) has a vital role in the analysis of the dynamic behavior of the rectangular tank. The results indicate that the flexibility of the tank walls has a significant impact on the amplitude of tank sloshing and the deformation of the free surface as well as the effect of liquid sloshing on wall deformation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arbitrary%20lagrangian-eulerian" title="arbitrary
