Soret And Dufour effects on an unsteady MHD mixed convective flow past an infinite vertical plate with Ohmic dissipation and heat source

Thermal-diffusion and diffusion-thermo effects on unsteady MHD mixed convection flow past an infinite vertical porous plate in the presence of chemical reaction, heat source and Joule effect have been studied numerically. A uniform magnetic field acts perpendicular to the porous surface. The governing non-linear partial differential equations have been transformed in to linear partial differential equations, which are solved numerically by applying explicit finite difference method. The effects of various parameters on the velocity, temperature, concentration, Nusselt number, Sherwood number and skin friction coefficient have been examined with the help of graphs and tables.
