Abstract
In this analysis, unsteady free convection flow of an electrically conducting fluid past an exponentially accelerated infinite vertical plate with constant heat flux through a porous medium is examined under the influence of uniform magnetic field fixed to the fluid or to the plate in the presence of chemical reaction and heat generation or absorption. The governing partial differential equations have been solved analytically with the aid of Laplace transform technique and the expression for the velocity, temperature and concentration were obtained. Results are presented to illustrate the influence of system parameters such as magnetic parameter, heat generation or absorption parameter, permeability parameter, Prandtl number, Grashof number, modified Grashof number, chemical reaction parameter.
