RÉSUMÉ

In this paper the influence of thermal diffusion (Soret) and diffusion thermo (Dufour) on an unsteady transient radiative MHD free convective heat transfer of a viscous, incompressible, and electrically conducting fluid past a suddenly started infinite vertical plate embedded in a porous medium is studied with the presence of a chemical reaction. The dimensionless governing, coupled, boundary layer partial differential equations (PDE's) are solved by an efficient finite element method (FEM) for velocity (u), temperature (θ), and concentration (φ) fields with the various thermophysical parameters for externally heating (Gr > 0) and cooling (Gr > 0) of the plate. Also from these computations, local skin friction, and rate of heat and mass transfer coefficients at the plate are obtained. The present results are in good agreement with earlier reported studies using the Laplace transform technique (LTT) and the present results are independent of mesh size.
