Abstract

In the present paper FEM and FDM analysis is made to analyze the effect of Dufour number variation on unsteady free convection flow of an electrically conducting, viscous fluid past an infinite vertical porous plate embedded in porous medium. Magnetic field is applied normal to the flow. The governing non-linear coupled partial differential equations with boundary conditions are solved using Galerkin finite element and Crank-Nicholson methods. Graphical results for velocity, temperature and concentration fields and tabular values of Skin-friction and Nusselt numbers are presented and discussed. It is observed that the velocity and Temperature, Skin–friction and Nusselt number increase in the presence of viscous dissipation and for the increasing values of Dufour number.
