ABSTRACT:

Influences of chemical reaction and radiation on unsteady magnetohydodynamic free convection flow of an electrically conducting fluid past an exponentially accelerated infinite vertical plate through a porous medium with constant heat flux under the presence of uniform magnetic field fixed relative to the fluid or to the plate in the consideration of heat absorption have been studied. The governing partial differential equations of the flow have been solved analytically by using Laplace transform technique and the profiles for the velocity, temperature and concentration were discussed. The effects of various physical parameters such as the Prandtl number, heat absorption parameter, radiation parameter, Grashof number, Chemical reaction parameter, magnetic field parameter and permeability parameters on the flow fields are analyzed through graphs.
