Abstract

The present paper examines the effect of thermal radiation on steady MHD
mixed convection over a vertical plate with a convective boundary condition embedded in
a porous medium. The effect of chemical reaction is also taken into account and hence
a first-order chemical reaction is considered. Firstly, the governing equations of fluid
have been written into a normalized form and then an implicit finite-difference scheme is
applied for solving the ordinary differential equations. Illustrative outcomes are obtained
to interpret the different physical parameters of interest. The results show that, for the
case Bi = 0, the skin-friction is almost constant for various values of radiation parameter
and no change in the Nusselt number takes place. However, for Bi > 0, increasing the
radiation parameter is leading to an increase in values of skin-friction and reduction in
values of Nusselt number.
