In these studies, the particle-wall no-slip boundary condition was usually adopted. However, the non-slip boundary condition is rarely encountered in real systems. A little effort has been made to investigate the particle behavior at slip boundary conditions. The paper represents a study of the gas-solid flow in a horizontal rotating drum at a slip boundary wall condition. Two different sizes of particles with the same density have been considered. The Eulerian鈥揈ulerian multiphase model with the kinetic theory of granular flow was used in the simulations. The granular pressure at the rolling flow regime with specularity coefficient 1 was examined and compared with that obtained based on the no-slip boundary condition. The results reveal that the profiles of granular pressure distribution on the transverse plane of the drum are similar for both boundary conditions. But, overall, compared with those for the no-slip boundary condition, the values of granular pressure for specularity coefficient 1 are larger for the larger particle and smaller for the smaller particle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boundary%20condition" title="boundary condition">boundary condition</a>, <a href="https://publications.waset.org/abstracts/search?q=eulerian%E2%80%93eulerian" title=" eulerian鈥揺ulerian"> eulerian鈥揺ulerian</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase" title=" multiphase"> multiphase</a>, <a href="https://publications.waset.org/abstracts/search?q=specularity%20coefficient" title=" specularity coefficient"> specularity coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=transverse%20plane" title=" transverse plane"> transverse plane</a> </p> <a href="https://publications.waset.org/abstracts/138424/effect-of-boundary-condition-on-granular-pressure-of-gas-solid-flow-in-a-rotating-drum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138424.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">219</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2432</span> Effects of Dispersion on Peristaltic Flow of a Micropolar Fluid Through a Porous Medium with Wall Effects in the Presence of Slip</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Ravi%20Kiran">G.

Long wavelength approximation, Taylor's limiting condition and dynamic boundary conditions at the flexible walls are used to obtain the average effective dispersion coefficient in the presence of combined homogeneous and heterogeneous chemical reactions. The effects of various pertinent parameters on the effective dispersion coefficient are discussed. It is observed that peristalsis enhances dispersion. It also increases with micropolar parameter, cross viscosity coefficient, Darcy number, slip parameter and wall parameters.

The present work considers the effects of velocity slip, temperature jump and suction/injection on the flow and heat transfer of power-law fluids due to a rotating disk in the presence of magnetic field. The system of the partial differential equations is highly non-linear. The number of independent variables is reduced by transforming the system into a system of coupled non-linear ordinary differential equations using similarity transformations. The effects of suction/injection, velocity slip and temperature jump on the flow rates are investigated for various cases of shear thinning and shear thickening power law fluids. The thermal and velocity jump strongly reduce the heat transfer rate and skin friction coefficient. Suction decreases the radial and tangential skin friction coefficient and the rate of heat transfer. It is also observed that the effects are more pronounced in the case of shear thinning fluids as compared to shear thickening fluids. <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=power-law%20fluids" title=" power-law fluids"> power-law fluids</a>, <a href="https://publications.waset.org/abstracts/search?q=rotating%20disk" title=" rotating disk"> rotating disk</a>, <a href="https://publications.waset.org/abstracts/search?q=suction%20or%20injection" title=" suction or injection"> suction or injection</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20jump" title=" temperature jump"> temperature jump</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity%20slip" title=" velocity slip"> velocity slip</a> </p> <a href="https://publications.waset.org/abstracts/53534/magnetohydrodynamics-flow-and-heat-transfer-in-a-non-newtonian-power-law-fluid-due-to-a-rotating-disk-with-velocity-slip-and-temperature-jump" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53534.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">2429</span> Influence of Hydrophobic Surface on Flow Past Square Cylinder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Ajith%20Kumar">S.

Rajan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In external flows, vortex shedding behind the bluff bodies causes to experience unsteady loads on a large number of engineering structures, resulting in structural failure. Vortex shedding can even turn out to be disastrous like the Tacoma Bridge failure incident. We need to have control over vortex shedding to get rid of this untoward condition by reducing the unsteady forces acting on the bluff body. In circular cylinders, hydrophobic surface in an otherwise no-slip surface is found to be delaying separation and minimizes the effects of vortex shedding drastically. Flow over square cylinder stands different from this behavior as separation can takes place from either of the two corner separation points (front or rear). An attempt is made in this study to numerically elucidate the effect of hydrophobic surface in flow over a square cylinder. A 2D numerical simulation has been done to understand the effects of the slip surface on the flow past square cylinder. The details of the numerical algorithm will be presented at the time of the conference. A non-dimensional parameter, Knudsen number is defined to quantify the slip on the cylinder surface based on Maxwell鈥檚 equation. The slip surface condition of the wall affects the vorticity distribution around the cylinder and the flow separation. In the numerical analysis, we observed that the hydrophobic surface enhances the shedding frequency and damps down the amplitude of oscillations of the square cylinder. We also found that the slip has a negative effect on aerodynamic force coefficients such as the coefficient of lift (CL), coefficient of drag (CD) etc. and hence replacing the no slip surface by a hydrophobic surface can be treated as an effective drag reduction strategy and the introduction of hydrophobic surface could be utilized for reducing the vortex induced vibrations (VIV) and is found as an effective method in controlling VIV thereby controlling the structural failures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drag%20reduction" title="drag reduction">drag reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20past%20square%20cylinder" title=" flow past square cylinder"> flow past square cylinder</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20control" title=" flow control"> flow control</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophobic%20surfaces" title=" hydrophobic surfaces"> hydrophobic surfaces</a>, <a href="https://publications.waset.org/abstracts/search?q=vortex%20shedding" title=" vortex shedding "> vortex shedding </a> </p> <a href="https://publications.waset.org/abstracts/27450/influence-of-hydrophobic-surface-on-flow-past-square-cylinder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27450.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">375</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">2428</span> Flow of a Second Order Fluid through Constricted Tube with Slip Velocity at Wall Using Integral Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nosheen%20Zareen%20Khan">Nosheen Zareen Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Majeed%20Siddiqui"> Abdul Majeed Siddiqui</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Afzal%20Rana"> Muhammad Afzal Rana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The steady flow of a second order fluid through constricted tube with slip velocity at wall is modeled and analyzed theoretically.

The studied parameters in this paper included the following: CFS beam section geometry, the value of slip force, CFS beam thickness. The numerical results indicate that CFS slotted bolted connection exhibit higher inelastic capacity in terms of ductility compare to connection with standards holes. Moreover, the effect of slip force was analysed by comparing the moment-rotation curves of different models with different slip force value. As a result, as the slip force became lower, there was a tendency for the plastic strain to extend from the CFS member to the connection region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=slip-critical%20bolted%20connection" title="slip-critical bolted connection">slip-critical bolted connection</a>, <a href="https://publications.waset.org/abstracts/search?q=inelastic%20capacity" title=" inelastic capacity"> inelastic capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=slotted%20holes" title=" slotted holes"> slotted holes</a>, <a href="https://publications.waset.org/abstracts/search?q=cold-formed%20steel" title=" cold-formed steel"> cold-formed steel</a>, <a href="https://publications.waset.org/abstracts/search?q=bolt%20slippage" title=" bolt slippage"> bolt slippage</a>, <a href="https://publications.waset.org/abstracts/search?q=slip%20force" title=" slip force"> slip force</a> </p> <a href="https://publications.waset.org/abstracts/59462/improving-inelastic-capacity-of-cold-formed-steel-beams-using-slotted-blotted-connection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59462.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">431</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">2426</span> Magnetohydrodynamic (MHD) Flow of Cu-Water Nanofluid Due to a Rotating Disk with Partial Slip</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tasawar%20Hayat">Tasawar Hayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Madiha%20Rashid"> Madiha Rashid</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Imtiaz"> Maria Imtiaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Alsaedi"> Ahmed Alsaedi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This problem is about the study of flow of viscous fluid due to rotating disk in nanofluid.

It is found that the skin friction coefficient and heat transfer rate at the surface are highest in copper-water nanofluid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MHD%20nanofluid" title="MHD nanofluid">MHD nanofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20medium" title=" porous medium"> porous medium</a>, <a href="https://publications.waset.org/abstracts/search?q=rotating%20disk" title=" rotating disk"> rotating disk</a>, <a href="https://publications.waset.org/abstracts/search?q=slip%20effect" title=" slip effect"> slip effect</a> </p> <a href="https://publications.waset.org/abstracts/55344/magnetohydrodynamic-mhd-flow-of-cu-water-nanofluid-due-to-a-rotating-disk-with-partial-slip" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55344.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">260</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">2425</span> Second-Order Slip Flow and Heat Transfer in a Long Isothermal Microchannel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huei%20Chu%20Weng">Huei Chu Weng</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Hung%20Liu"> Chien-Hung Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a study on the effect of second-order slip and jump on forced convection through a long isothermally heated or cooled planar microchannel.

The fluid is assumed to be viscoelastic PTT (Phan-Thien and Tanner). The rheological constitutive equation of PTT fluid model simulates various polymer melts. Therefore, the current consequences are valuable in a number of realistic situations. Effects of slip parameter 纬 as well as 蔚Dec^2 (viscoelastic index) on the axial velocity, shear stress, normal stress, average velocity, volume flux, thickness of coated wire, shear stress, force on the total wire and temperature distribution profiles have been investigated. A new direction is explored to analyze the flow with the slip parameter. The slippage at the boundaries plays an important role in thickness of coated wire. It is noted that as the slip parameter increases the flow rate and thickness of coated wire increases while, temperature distribution decreases. The results reduce to no slip when the slip parameter is vanished. Furthermore, we can obtain the results for Maxwell and viscous model by setting 蔚 and 位 equal to zero respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wire%20coating" title="wire coating">wire coating</a>, <a href="https://publications.waset.org/abstracts/search?q=straight%20annular%20die" title=" straight annular die"> straight annular die</a>, <a href="https://publications.waset.org/abstracts/search?q=PTT%20fluid" title=" PTT fluid"> PTT fluid</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=slip%20boundary%20conditions" title=" slip boundary conditions"> slip boundary conditions</a> </p> <a href="https://publications.waset.org/abstracts/42279/analysis-of-wire-coating-for-heat-transfer-flow-of-a-viscoelastic-ptt-fluid-with-slip-boundary-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42279.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">363</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">2420</span> Experimental Modelling Gear Contact with TE77 Energy Pulse Setup</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zainab%20Mohammed%20Shukur">Zainab Mohammed Shukur</a>, <a href="https://publications.waset.org/abstracts/search?q=Najlaa%20Ali%20Alboshmina"> Najlaa Ali Alboshmina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Safa%20Alsaegh"> Ali Safa Alsaegh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The project was investigated tribological behavior of polyether ether ketone (PEEK1000) against PEEK1000 rolling sliding (non-conformal) configuration with slip ratio 83.3%, were tested applications using a TE77 wear mechanisms and friction coefficient test rig. Under marginal lubrication conditions and the absence of film thick conditions, load 100 N was used to simulate the torque in gears 7 N.m. The friction coefficient and wear mechanisms of PEEK were studied under reciprocating roll/slide conditions with water, ethylene glycol, silicone, and base oil. Tribological tests were conducted on a TE77 high-frequency tribometer, with a disc-on-plate slide/roll (the energy pulse criterion) configuration. An Alicona G5 optical 3D micro-coordinate measurement microscope was used to investigate the surface topography and wear mechanisms. The surface roughness had been a significant effect on the friction coefficient for the PEEK/PEEK the rolling sliding contact test ethylene glycol and on the wear mechanisms. When silicone, ethylene glycol, and oil were used as a lubricant, the steady state of friction coefficient was reached faster than the other lubricant.

By implementing the Navier-slip model and a lubrication-type approach into the equations which govern the dynamic response of a drop exposed to acoustic stress, a highly nonlinear evolution equation for the air-liquid interface is derived in terms of the acoustic capillary number and the slip coefficient. By numerically solving such an evolution equation, the Spatio-temporal deformation of the drop's free surface is obtained; in this context, atomization of the initial drop into micron-sized droplets is predicted at our numerical model once the acoustically-driven capillary waves reach a critical value: the instability length. Our results show slippage phenomenon at systems with partial and complete wetting favors the formation of capillary waves at the free surface, which traduces in a major volume of liquid being atomized in comparison to the no-slip case for a given time interval. In consequence, slippage at the wall possesses the capability to affect and improve the atomization rate for a drop exposed to a high-frequency acoustic field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capillary%20instability" title="capillary instability">capillary instability</a>, <a href="https://publications.waset.org/abstracts/search?q=lubrication%20theory" title=" lubrication theory"> lubrication theory</a>, <a href="https://publications.waset.org/abstracts/search?q=navier-slip%20condition" title=" navier-slip condition"> navier-slip condition</a>, <a href="https://publications.waset.org/abstracts/search?q=SAW%20atomization" title=" SAW atomization"> SAW atomization</a> </p> <a href="https://publications.waset.org/abstracts/121113/capillary-wave-motion-and-atomization-induced-by-surface-acoustic-waves-under-the-navier-slip-condition-at-the-wall" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121113.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">156</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">2418</span> The Superhydrophobic Surface Effect on Laminar Boundary Layer Flows</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chia-Yung%20Chou">Chia-Yung Chou</a>, <a href="https://publications.waset.org/abstracts/search?q=Che-Chuan%20Cheng"> Che-Chuan Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Chin%20Chi%20Hsu"> Chin Chi Hsu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Hui%20Wu"> Chun-Hui Wu </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigates the fluid of boundary layer flow as it flows through the superhydrophobic surface.

The temperature and the chemical species concentration of the surface and the velocity of the external flow are assumed to vary linearly with the distance from the vertical surface. The governing differential equations are modeled and transformed into systems of ordinary differential equations, which are then solved numerically by a shooting method. The effects of various parameters on the heat and mass transfer characteristics are discussed. Graphical results are presented for the velocity, temperature, and concentration profiles whilst the skin-friction coefficient and the rate of heat and mass transfers near the surface are presented in tables and discussed. The results revealed that increasing the strength of the magnetic field increases the skin-friction coefficient and the rate of heat and mass transfers toward the surface. The velocity profiles are increased towards the surface due to the presence of the Lorenz force, which attracts the fluid particles near the surface. The rate of chemical reaction is seen to decrease the concentration boundary layer near the surface due to the destructive chemical reaction occurring near the surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boundary%20layer" title="boundary layer">boundary layer</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20slip" title=" surface slip"> surface slip</a>, <a href="https://publications.waset.org/abstracts/search?q=MHD%20flow" title=" MHD flow"> MHD flow</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20reaction" title=" chemical reaction"> chemical reaction</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=mass%20transfer" title=" mass transfer"> mass transfer</a> </p> <a href="https://publications.waset.org/abstracts/36170/mhd-chemically-reacting-viscous-fluid-flow-towards-a-vertical-surface-with-slip-and-convective-boundary-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36170.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">539</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">2416</span> Slip Suppression Sliding Mode Control with Various Chattering Functions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shun%20Horikoshi">Shun Horikoshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tohru%20Kawabe"> Tohru Kawabe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents performance analysis results of SMC (Sliding mode control) with changing the chattering functions applied to slip suppression problem of electric vehicles (EVs). In SMC, chattering phenomenon always occurs through high frequency switching of the control inputs. It is undesirable phenomenon and degrade the control performance, since it causes the oscillations of the control inputs. Several studies have been conducted on this problem by introducing some general saturation function. However, study about whether saturation function was really best and the performance analysis when using the other functions, weren鈥檛 being done so much. Therefore, in this paper, several candidate functions for SMC are selected and control performance of candidate functions is analyzed. In the analysis, evaluation function based on the trade-off between slip suppression performance and chattering reduction performance is proposed. The analyses are conducted in several numerical simulations of slip suppression problem of EVs. Then, we can see that there is no difference of employed candidate functions in chattering reduction performance. On the other hand, in slip suppression performance, the saturation function is excellent overall. So, we conclude the saturation function is most suitable for slip suppression sliding mode control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode%20control" title="sliding mode control">sliding mode control</a>, <a href="https://publications.waset.org/abstracts/search?q=chattering%20function" title=" chattering function"> chattering function</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle" title=" electric vehicle"> electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=slip%20suppression" title=" slip suppression"> slip suppression</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20analysis" title=" performance analysis"> performance analysis</a> </p> <a href="https://publications.waset.org/abstracts/75656/slip-suppression-sliding-mode-control-with-various-chattering-functions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75656.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">326</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">2415</span> MP-SMC-I Method for Slip Suppression of Electric Vehicles under Braking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tohru%20Kawabe">Tohru Kawabe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a new SMC (Sliding Mode Control) method with MP (Model Predictive Control) integral action for the slip suppression of EV (Electric Vehicle) under braking is proposed.

Based on the flow velocity field developed under such conditions, the present study implements an analytical scheme of scaling known as the Theory of Homogenization, in order to obtain a mathematical expression for the dispersivity, valid at a large time scale where the initial transients have vanished and the solute spreads under the Taylor dispersion influence. Our results show the dispersivity is a function of a slip coefficient, the amplitude of the imposed electric field, the Debye length and the angular Reynolds number, highlighting the importance of the latter as an enhancement/detrimental factor on the dispersivity, which allows to promote the PEOF as a strong candidate for chemical species separation at lab-on-a-chip devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dispersivity" title="dispersivity">dispersivity</a>, <a href="https://publications.waset.org/abstracts/search?q=microcapillary" title=" microcapillary"> microcapillary</a>, <a href="https://publications.waset.org/abstracts/search?q=Navier-slip%20condition" title=" Navier-slip condition"> Navier-slip condition</a>, <a href="https://publications.waset.org/abstracts/search?q=pulsatile%20electroosmotic%20flow" title=" pulsatile electroosmotic flow"> pulsatile electroosmotic flow</a>, <a href="https://publications.waset.org/abstracts/search?q=Taylor%20dispersion" title=" Taylor dispersion"> Taylor dispersion</a>, <a href="https://publications.waset.org/abstracts/search?q=Theory%20of%20Homogenization" title=" Theory of Homogenization"> Theory of Homogenization</a> </p> <a href="https://publications.waset.org/abstracts/95021/influence-of-a-pulsatile-electroosmotic-flow-on-the-dispersivity-of-a-non-reactive-solute-through-a-microcapillary" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95021.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">215</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">2413</span> Unsteady MHD Thin Film Flow of a Third-Grade Fluid with Heat Transfer and Slip Boundary Condition Down an Inclined Plane</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20M.%20Aiyesimi">Y.

The slip behavior is simulated by modifying material properties of steel element contacting concrete according to the derived formulation. Decreased elastic modulus simulates the slip occurrence at the interface and decreased yield strength simulates drop in load capacity of the structure.

In order to generate a large number of physically self-consistent rupture models, whose rupture process is consistent with the spatio-temporal heterogeneity of past earthquakes, we use multicycle simulations under the heterogeneous rate-and-state (RS) friction law for a 45deg dip-slip fault. We performed a parametrization study by fully dynamic rupture modeling, and then, a set of spontaneous source models was generated in a large magnitude range (Mw > 7.0). In order to validate rupture models, we compare the source scaling relations vs. seismic moment Mo for the modeled rupture area S, as well as average slip Dave and the slip asperity area Sa, with similar scaling relations from the source inversions. Ground motions were also computed from our models. Their peak ground velocities (PGV) agree well with the GMPE values. We obtained good agreement of the permanent surface offset values with empirical relations. From the heterogeneous rupture models, we analyzed parameters, which are critical for ground motion simulations, i.e. distributions of slip, slip rate, rupture initiation points, rupture velocities, and source time functions. We studied cross-correlations between them and with the friction weakening distance Dc value, the only initial heterogeneity parameter in our modeling. The main findings are: (1) high slip-rate areas coincide with or are located on an outer edge of the large slip areas, (2) ruptures have a tendency to initiate in small Dc areas, and (3) high slip-rate areas correlate with areas of small Dc, large rupture velocity and short rise-time. <p class="card-text"><strong>Keywords:</strong> <a
