Dufour and Soret effect on MHD convective fluid flow in a vertical porous plate with suction

Abstract

The present paper is aimed at numerical investigation on the problem of heat and mass transfer on MHD boundary layer with chemical reaction, suction, Soret and Dufour effects. The properties of the fluid considered in present numerical study have been assumed to constant and the variation of density with buoyancy force is also analysed. The governing equations of the flow are transformed into non-linear ordinary differential equations and then solved by using Keller-box method. The various parameters like Magnetic parameter (M), thermal Grashof number (Gr), mass Grashof number (Gc), permeability parameter (K), Prandtl number (Pr), Dufour number (Du), Soret number (Sr) on the flow are analyzed and shown in graphs. The numerical values of the Skin friction coefficient, Nusselt number and the Sherwood number are tabulated.
