Combined effect of internal heat generation and magnetic field on free convection and mass transfer flow in a micropolar fluid with constant suction

Abstract

This paper studied the problem of free convection with mass transfer flow for a micropolar fluid bounded by a vertical infinite surface with an exponentially decaying heat generation, under the action of a transverse magnetic field. Numerical calculations are carried out for the various parameters entering into the problem. The numerical values of the skin friction, the wall couple stress, the rate of heat transfer, the concentration gradient at the wall and the boundary layer thickness are shown graphically as functions of the magnetic field parameter.
