Abstract

This work investigates the effects of internal heat generation and suction or injection parameter on a chemically reacting heat and mass MHD fluid flow over a permeable surface with convective boundary conditions. By transforming the system of coupled partial differential equations governing the flow into a system of coupled ordinary differential equations using similarity transformation, the resulting ordinary differential equations are solved using the Fourth order Runge-Kutta method with shooting technique. Increase in fluid suction retards rate of transportation but decrease the boundary layer thickness and vice versa for fluid injection. Internal heat generation increases fluid temperature and thickening of the thermal boundary layer.
