DOUBLE DIFFUSIVE FREE CONVECTION PROCESS INDUCED BY BOUNDARY LAYER FLOW ALONG A VERTICAL SURFACE IN A DOUBLY STRATIFIED FLUID SATURATED POROUS MEDIUM WITH SORET AND DUFOUR EFFECTS UNDER MHD FORCES
This paper details a study of the combined effect of heat and mass transfer in a two-dimensional mag-netohydrodynamic free convection flow along a vertical semi-infinite flat surface immersed in a thermal and mass stratified Darcy porous medium under the influence of Soret and Dufour effect. The resulting nonlinear partial differential equations governing the problem under consideration have been transformed by a similarity transformation into a system of ordinary differential equations which are solved numerically by finite difference scheme following the Keller Box approach. A comparison with previously published work is performed and the results are found to be in good agreement. The numerical results are demonstrated graphically for various values of the parameters involved in the problem like: Magnetic parameter(Mg), Buoyancy ratio(B), Lewis number(Le), Soret(Sr) and Dufour(Df) numbers, presence of Thermal(Sr) and Mass(Sc) stratification. Local and Average Nusselt(Nu) number and Sherwood(Sh) number plots are presented in all cases..
