Abstract: Unsteady MHD free convective flow of a viscous, incompressible, electrically conducting and heat absorbing fluid past an infinite vertical porous plate with ramped wall temperature is analyzed in this effort with the control behavior of thermal diffusion and chemical reaction. The flow characteristics are worked out by adopting Laplace Transform procedure. Comprehensive computations of the influence of Soret number and chemical reaction on the variations in the fluid transport equations with viscous drag, Nusselt number and Sherwood number at the plate are established. Graphical demonstrations are incorporated for different values of the physical parameters with their physical relevance. The investigation reveals the fact that thermal diffusion has both enhancing and opposing influence on fluid velocity.
