Laminar effect of hall currents on mhd free convective flow of stratified viscous fluid past a porous vertical plate

In present paper is study of an unsteady MHD free convection of an incompressible, electrically conducting, laminar, viscous stratified liquid in a porous medium past a vertical porous isothermal infinite plate fluctuating with hall currents and time dependent suction velocity is presented. The flow is considered under the influence of transversely applied uniform magnetic field. It is assumed that the magnetic Reynolds number is very small so that the induced magnetic field is negligible. To obtain the solution for the velocity field and temperature field of the problem. The skin-friction coefficients and Nusselt number are also obtained. The results obtained are discussed graphically and numerically.
