• DIFFUSION-THERMO EFFECTS ON MHD FLOW PAST AN INFINITE VERTICAL POROUS PLATE IN THE PRESENCE OF RADIATION AND CHEMICAL REACTION

Abstract

The objective of the present study is to investigate the effect of flow parameters on the free convection and mass transfer of an unsteady magnetohydrodynamic flow of an electrically conducting, viscous, and incompressible fluid past an infinite vertical porous plate under oscillatory suction velocity and thermal radiation. The Dufour (diffusion thermo) and Chemical reaction effects are taken into account. The problem is solved numerically using the perturbation technique for the velocity, the temperature, and the concentration field. The expression for the skin friction, Nusselt number and Sherwood number are obtained. The effects of various thermo-physical parameters on the velocity, temperature and concentration as well as the skin-friction coefficient, Nusselt number and Sherwood number has been computed numerically and discussed qualitatively.
