UNSTEADY MHD FREE CONVECTION FLOW PAST AN EXPONENTIALLY ACCELERATED VERTICAL PLATE WITH MASS TRANSFER, CHEMICAL REACTION AND THERMAL RADIATION

This paper is concerned with the study of an unsteady, MHD free convective boundary layer flow of a viscous, incompressible and electrically conducting, chemically reacting fluid over an exponentially accelerated infinite vertical plate embedded in a porous medium in the presence of thermal diffusion, radiation and temperature dependent heat source or sink. The fluid considered is a gray, absorbing/emitting radiation but non scattering medium. The dimensionless governing equations for this investigation are solved analytically using the Laplace transform technique. Numerical evaluation of the analytical results is performed and graphical results for the velocity, temperature and concentration profiles within the boundary layer are presented graphically and discussed. Also, the expressions for the skin-friction coefficient, Nusselt number and the Sherwood number have been derived and plotted for different values of the governing parameters
