Abstract

Unsteady MHD Free convective two immiscible fluid flow through a Horizontal channel with Heat and mass transfer have been studied in this paper. The effect of Soret is also taken into account. The equations are solved analytically and numerically with the appropriate boundary conditions for each fluid and the solutions have been studied. The governing equations of the flow were transformed into ordinary differential equations by a regular perturbation method and the expression for the velocity; temperature and concentration for each fluid flow were obtained. The effects of various parameters like Grashof numbers for heat and mass transfer, Prandtl number, Viscosity ratio, Conductivity ratio, Radiative parameter, Soret number etc. on the velocity, temperature and concentration fields have been presented graphically.
