radiation and mass transfer effects on mhd oscillatory flow in a channel filled with porous medium in the presence of chemical reaction

The interaction of radiation and mass transfer in an electrically conducting fluid through a channel filled with porous medium has received little attention. hence, an attempt is made to investigate the combined effects of a transverse magnetic field and radiation on an unsteady mass transfer flow with chemical reaction through a channel filled with saturated porous medium and non-uniform wall temperature. the equations of continuity, linear momentum, energy and diffusion, which govern the flow field, are solved by using an analytical method. the behaviour of the velocity, temperature, concentration, skin-friction, nusselt number and sherwood number has been discussed for variations in the governing parameters.
