• INFLUENCE OF HALL CURRENTS ON CROSS DIFFUSIVE CONVECTION IN A MHD BOUNDARY LAYER FLOW ON STRETCHING SHEET IN POROUS MEDIUM WITH HEAT GENERATION

Abstract

An analysis has been carried out to investigate the effects of Hall currents, heat absorption/generation, cross diffusion by the simultaneous action of mass flux due to temperature gradient (Soret effect) and heat flux (Dufour effect) in the boundary layer flow past a linearly stretching sheet embedded in a porous medium in the presence of thermal radiation and first order chemical reaction. The partial differential equations governing the flow are transformed into a set of coupled non – linear ordinary differential equations employing similarity variables which are solved numerically applying shooting technique with Runge – Kutta fourth order scheme. The results of the present analysis are compared with those available in literature and are found to be in good agreement. The numerical results pertaining to velocity, temperature and mass concentration distributions of the flow, the local skin friction coefficient, local Nusselt number and local Sherwood number are graphically presented and discussed for various governing parameters such as magnetic parameter, Hall parameter, porous parameter etc.,
