Hall Current Effect on Visco-elastic Mhd Oscillatory Convective Flow through a Porous Medium in a Vertical Channel with Heat Radiation

Hall current effect on visco-elastic MHD oscillatory convective flow through a porous medium in a vertical channel with heat radiation is investigated. An oscillatory MHD convection flow of visco-elastic, incompressible, electrically conducting fluid in a vertical channel filled with porous medium in the presence of Hall currents is studied analytically. A magnetic field of uniform strength is applied in the direction normal to the planes of the plates. The temperature of one of the plates varies periodically and the temperature difference of the plates is high enough to induce heat transfer due to radiation. A closed form solution of the problem is obtained. The effects of various parameters on the velocity profiles, the skinfriction in terms of the amplitude and the phase angle are shown graphically and discussed in detail.
