Viscoelastic Effects on Unsteady Two-Dimensional and Mass Transfer of a Viscoelastic Fluid in a Porous Channel with Radiative Heat Transfer

Abstract

<p class="MsoNormal" style="text-align:justify;"> <span lang="EN-US">An analysis of oscillatory flow of a viscoelastic fluid and mass transfer along a porous oscillating channel with radiative heat transfer in presence of first-order chemical reaction is considered. The problem is concerned with the flow through a channel in which the viscoelastic fluid is injected on one boundary of the channel with a constant velocity, while it is sucked off at the other boundary with the same velocity. The two boundaries are considered to be in close contact with the two plates placed parallel to each other. The effect of temperature oscillations at the plate (upper wall) where the suction takes place is taken into consideration. The plates are supposed to be oscillating with a given velocity in their own planes. Analytical expressions for velocity profile, the temperature, concentration profile, wall shear stress on the upper wall are obtained. The profiles of the velocity and skin friction have been presented graphically for different values of the viscoelastic parameters with the combination of the other flow parameters encountered in the problem under investigation. It is observed that </span><span lang="EN-IN">velocity decrease with the increasing values of the viscoelastic parameter in comparison with Newtonian fluid. Also, the wall shear stress increase with the increasing values of the viscoelastic parameter.</span><span lang="EN-US"><o:p></o:p></span> </p

Oscillatory Fluid Flow and Heat Transfer Through Porous Medium Between Parallel Plates with Inclined Magnetic Field, Radiative Heat Flux and Heat Source

“…Singh [13] described a viscoelastic mixed convection MHD oscillatory flow through a porous medium filled in a vertical channel. Das [14] presented viscoelastic effects on unsteady two dimensional heat and mass transfer of a viscoelastic fluid in a porous channel with radiative heat transfer. Sandeep and Sugunamma [15] discussed the effect of an inclined magnetic field on an unsteady free convection flow of a dusty viscous fluid between two infinite flat plates filled by a porous medium.…”

Influence of Couple Stresses and Thermophoresis on Free Convective Heat and Mass Transfer of Viscoelastic Fluid.

“…Uddin et al [2] have investigated effects of hydromagnetic and thermophoresis of unsteady forced convection boundary layer flow over flat plates. The analysis of viscoelastic fluid flow on unsteady two-dimensional in a porous channel with radiative heat transfer and mass transfer has been studied by Das [3]. Sudhakar et al [4] have studied heat and mass transfer on unsteady free convection of a Walters-B viscoelastic fluid flow past a semi infinite plate under thermophoresis effect.…”

Application of Caputo-Fabrizio Fractional Order Derivative (NFDt) in Simulating the MHD Flow of the Third Grade non-Newtonian Fluid in the Porous Artery

“…According to Bao et al [6], their non-contact technique (in which the free surface flow of liquid oxygen was controlled by employing the non-uniform magnetic field) could develop the interface renewal and, minimize the resistance of flow inside the cryogenic distillation column by refining the flow uniformity, (more effective than air separation of cryogenic). According to Das [7] highlighted that increased viscoelastic parameter would decrease the flow velocity. However, by increasing the porosity and the mass Garashof number, the flow velocities of both Newtonian and non-Newtonian fluids increased significantly.…”
