Hydromagnetic Flow with Dufour and Soret Effects past a Vertical Plate Embedded in Porous Media

Abstract

The effect of thermal diffusion and diffusion thermo on mixed convection MHD flow past a semi-infinite vertical porous plate embedded in a porous medium with viscous and Ohmic dissipation is investigated. The governing equations of the problem are transformed to ordinary differential equations using similarity variables and then solved numerically by the fourth-order Runge-Kutta-Fehlberg method with shooting technique. Numerical results showing the effects of various thermophysical parameters on the local skin-friction coefficient, the local Nusselt number and the local Sherwood numbers are presented in tables whilst graphical illustrations for the velocity, temperature and concentration profiles are presented and discussed quantitatively.
