• EFFECT OF POROSITY ON SIMULTANEOUS THERMAL AND MASS DIFFUSION IN MHD MIXED CONVECTION FLOW OVER A VERTICAL SURFACE

Abstract

The influence of porosity and radiation on simultaneous thermal and mass diffusion of an electrolytic solution past a hot vertical plate with ohmic heating and magnetic field has been examined in this paper.It is observed that, as the porosity of the bounding surface increases the velocityalsoincreases.Also, the velocity is found to be decreasing as the modified Grashoff number decreases. Further, due to increase in the porosity, the velocity is observed to be decreasing. In general it is observed that, the skin friction increases as the Grashoff number increases. In addition to the above it is observed that as magnetic field intensity is increases the skin friction decreases. Further, it is seen that the magnetic field intensity and skin friction are inversely related.
