Transient mhd mass transfer flow past an impulsively started vertical plate in a porous medium with ramped temperature, thermal diffusion and radiation

In this paper we discuss, an exact solution to the problem of a MHD viscous, incompressible free convective flow of an electrically conducting, Newtonian non Grey fluid past a suddenly started infinite vertical plate with ramped wall temperature and concentration in presence of appreciable radiation heat transfer and uniform transverse magnetic field is presented. The fluid is assumed negligible magnetic Reynolds number considered Induced hydro magnetic effects. The equations governing the flow are solved by using Laplace transform technique in closed form. The influence of Hartmann number, radiation parameter, Darcy number, Reynolds number and time on the variations in the fluid velocity, fluid temperature, fluid concentration, skin friction, Nusselt number and Sherwood number at the plate are demonstrated graphically and physically interpreted.
