MHD free convection flow past a vertical porous plate in a slip flow regime with radiation chemical reaction and temperature gradient dependent heat source in presence of Dufour effect

Abstract

This paper deals with the MHD free convection flow past a vertical porous plate in a slip flow regime taking into account radiation ,chemical reaction and temperature gradient dependent heat source in presence of Dufour effect. The magnetic effect is applied normal to the flow. The permeability of the porous medium and the suction velocity at the plate decrease exponentially with time about a constant mean. The expression for velocity, temperature and concentration are obtained using the regular perturbation method. The skin-friction, rate of heat and mass transfer are also derived. A number of graphs are drawn for various flow quantities based on governing parameters and deduce important results.
