Effect of chemical reaction on unsteady MHD free convective two immiscible fluids flow

Abstract

The effect of chemical reaction on unsteady MHD free convective two immiscible fluids flow has been studied. Approximate analytical solutions to the governing equations are found for the coupled and linear differential equations using regular perturbation method. Graphs depicting the effect of chemical reaction parameter ?_? and others flow parameters on velocity, temperature and concentration profiles are obtained and
discussed accordingly. The effect of flow parameters on the coefficient of skin friction, Nusselt number and Sherwood number are also tabulated and discussed appropriately. It was observed that the increase in chemical reaction coefficient/parameter ?_? suppresses both velocity and concentration profiles.
