THE SORET EFFECT ON FREE CONVECTIVE UNSTEADY MHD FLOW OVER A VERTICAL PLATE WITH HEAT SOURCE

Abstract

The work is focused on free convective an unsteady MHD flow in a vertical plate with heat source, thermo diffusion (Soret effect) and the influence of the thermal radiation on hydromagnetic for a viscous fluid past a semi-infinite vertical moving porous plate embedded in a porous medium. The plate moves with constant velocity in the direction of fluid flow while the free stream velocity is assumed to follow the exponentially increasing small perturbation law. The external flow field is assumed to be uniform and the effect of the Soret parameter in the boundary layer adjacent to the vertical plate with fluid suction/injection through it is analyzed in both aiding and opposing flow situations. The dimensionless governing equations for this investigation are solved analytically by using perturbation technique. The effects of various parameters on the velocity, temperature and concentration fields as well as the skinfriction coefficient, Nusselt number and the Sherwood number are presented graphically detail.
