Rotating convective MHD flow over a vertical moving plate in the presence of heat source, radiation, chemical reaction and Hall effects

Abstract

The steady MHD rotating flow and heat mass transfer over a semi-infinite vertical plate moving with a constant velocity in the presence of a heat source, thermal radiation, first-order chemical reaction and Hall effect are studied. The methodology proposed to predict the velocity, temperature and concentration evolutions is based on similarity transformation and finite difference method. The simulation has been carried out for different pertinent parameters of problem. The main results are that the velocity fields are considerably affected by the velocity ratio and coriolis parameters. Except the axial w-velocity that increases only near the plate with the velocity ratio parameter, all the velocities decrease as the velocity ratio and Coriolis parameters increase, whereas the temperature and the concentration profiles increase. Also, the fluid velocity and temperature increase when the heat source and radiation parameters increase but the concentration decreases.
