MHD free convection and mass transfer flow of a micro-polar thermally radiating and reacting fluid with time dependent suction

Abstract

The problem of free convection of a chemically reacting micro-polar fluid with mass transfer has been studied in the presence of a uniformly applied transverse magnetic field and variable suction. The governing, coupled, non-linear partial differential equations are solved employing a fourth order Runge-Kutta algorithm. The results show that the velocity increases as the suction parameter is increased, the chemical reaction rate decreases; while the angular velocity increases with increasing values of the suction parameter up to a point around y = 1.5, before the trend is reversed.
