THERMAL DIFFUSION EFFECT ON MHD FREE CONVECTIVE HEAT ABSORBINGFLUID WITH VARIABLE TEMPERATURE AND CONCENTRATION

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 solved numerically by using finite difference scheme. The effects of different physical parameters on velocity, temperature and concentration are presented and discussed with the help of graphs. Also the numerical values for local skin friction, Nusselt number and Sherwood number are recorded and analyzed. Increasing values of Soret number results in rising of the concentration, but it falls down under the influence of Schmidt number. Skin friction decreases for increasing values of Soret number.
