UNSTEADY MHD FREE CONVECTIVE MASS TRANSFER FLOW PAST AN INFINITE VERTICAL POROUS PLATE WITH VARIABLE SUCTION AND SORET EFFECT

Abstract

The MHD effects on the unsteady heat convective mass transfer flow past an infinite vertical porous plate with variable suction, where the plate temperature oscillates with the same frequency as that of variable suction velocity with the Soret eflects. The governing equations of motion are solved to best possible classical solution by assuming at suitable trial solution. The flow phenomenon has been characterized with the help of flow parameters such as velocity, temperature and concentration profiles for diflerent parameters such as Grashof number (Gr), modified Grashof number (Gm), Schmidt number (Sc), Prandtl number (Pr), Soret number (SO), Magnetic field (M) and variable suction parameter (A). The velocity, temperature and concentration profiles and ski-friction are shown graphically.
