Effect of Thermal Conductivity on Mhd Heat and Mass Transfer: Flow Past an Infinite Vertical Plate with Soret and Dufour Effects

Abstract

This paper investigates the study of the effect of thermal conductivity on MHD flow past an infinite vertical plate with Soret and Dufour effects. The governing non-linear Partial Differential Equations are solved numerically by implicit finite difference scheme of Crank-Nicolson. Computations are performed for a wide range of the governing flow parameters such as thermal Grashof number, solutal Grashof number, magnetic field parameter, Prandtl number, Dufour number, Soret number, thermal conductivity and Schmidt number. The effects of these flow parameters on the velocity, temperature and concentration are shown graphically. It is observed that the velocity increases with the increase in Gr, Gc, Du, Ec, k and and it decreases with the increase in M, Sr and b. Temperature decreases with an increase in and Pr and concentration decreases with the increase in Sr and . Finally, the effects of various parameters on the skin friction coefficient, Nusselt number and Sherwood number are shown on Tables.
