Radiation and Magnetohydrodynamics Effects on Unsteady Free Convection Flow in a Porous Medium

Abstract EN

The unsteady MHD free convection flow near an exponentially accelerated infinite vertical plate through porous medium with uniform heat flux in the presence of thermal radiation has been considered.

The mathematical model, under the usual Boussinesq approximation, was reduced to a system of coupled linear partial differential equations for velocity and temperature.

Exact solutions are obtained by the Laplace transform method.

The influence of pertinent parameters such as the radiation parameter, Grashof number, Prandtl number, and time on velocity, temperature, and skin friction is shown by graphs.
