Magnetohydrodynamic Convective Double Diffusive Laminar Boundary Layer Flow Past an Accelerated Vertical Plate

Abstract

This manuscript presents the diffusion thermo and thermo diffusion effects on unsteady MHD natural convection heat and mass transfer flow past an accelerated vertical porous plate in the presence of thermal radiation, variable temperature and also variable concentration. The non-dimensional governing equations are coupled non-linear partial differential equations for which the exact solution is not possible. Hence these equations are solved numerically by using finite difference scheme. The effects of different physical parameters involved in the problem are presented and discussed with the help of graphs. The fluid velocity increases with the increasing values of Grashof number, modified Grashof number, Soret number, Dufour number and permeability of the porous medium, but a reverse behavior is found in the case of magnetic parameter and Prandtl number. The fluid temperature falls down for increasing values of radiation parameter, heat sink parameter and Prandtl number, whereas enhancement in the fluid temperature is found in the case of Soret and Dufour effects. Increasing values of Soret number results in rising of the concentration, but it falls down under the influence of Dufour number and Schmidt number.

Finite element Soret Dufour effects on an unsteady MHD heat and mass transfer flow past an accelerated inclined vertical plate

“…Some researchers have investigated different areas regarding this, for instance, Chamkha and Khaled 1 analyzed the hydromagnetic simultaneous solution of natural convective heat and mass from an inclined plate in the presence of internal heat generation/absorption. The MHD double‐diffusive laminar boundary layer flow over an accelerating vertical plate was examined by Reddy et al 2 Tripathy et al 3 analyzed the chemical reaction effect on the free convective surface of the MHD. Kandasamy et al 4 studied several effects of the MHD flow over a stretching sheet.…”

Unsteady MHD Heat and Mass Transfer Flow of a Radiating Fluid Past an Accelerated Inclined Porous Plate With Hall Current

“…Convective ramped temperature and concentration boundary layer flow of a chemically reactive heat absorbing and radiating fluid over a vertical plate in conducting field with Hall current was considered by Reddy et al [27]. Magnetohydrodynamic convective double diffusive laminar boundary layer flow past an accelerated vertical plate was considered by Chandra et al [28]. Hall current effects on unsteady MHD flow in a rotating parallel plate channel bounded by porous bed on the lower half Darcy lap wood model were investigated by Harikrishna et al [29].…”
