RÉSUMÉ

An analysis is presented to investigate the effects of chemical reaction, heat generation, the Soret and Dufour numbers on free convective heat and mass transfer of a viscous incompressible electrically conducting fluid on an inclined stretching surface in a porous medium. Three conditions are considered, namely, the isothermal surface, plane plume, flow generated by horizontal energy source and vertical adiabatic surface. By the similarity transformation, governing partial differential equations have been transformed into a system of ordinary differential equations, which are solved numerically using the fourth-order Runge - Kutta scheme with shooting method. The obtained results show that the flow field is appreciably influenced by presence of chemical reaction, permeability parameter, Dufour number and the angle of an inclined surface.
