Abstract
-This paper explores the effects of Arrhenius activation
energy on a chemically reactive MHD flow through a porous
surface while considering the joule heating effect of the
two-dimensional free convective flow. The study incorporates
the impact of the activation energy on the flow, the effect of the
chemical reaction rate parameter on the velocity and
temperature profiles as well as the joule heating parameter on
the flow. The concentration of the species in the fluid will be
investigated and the results discussed. The resulting non-linear
partial differential equations are solved using the finite
difference methods and results displayed graphically to show the
effects of the resulting dimensionless parameters. It is found that
the presence of the chemical reaction rate parameter on the flow
decreases the concentration of the fluid while the activation
energy shows the converse results.
