Hall effect on heat and mass transfer in the flow of oscillating viscoelastic fluid through porous medium with wall slip conditions

Abstract

The Hall current and slip conditions effects on heat and mass transfer of a general unsteady hydromagnetic, free convective flow of viscoelastic fluid (Walter’s B-model) past an infinite vertical porous plate subjected to uniform suction through porous medium, have been investigated theoretically. The temperature and the concentration at the plate are assumed to be oscillating with time. The solutions of the governing equations for the velocity, temperature and the concentration fields are obtained in the closed form. The significant effects of the various parameters entering into the problem on the velocity and the skin friction fields have been evaluated numerically and expressed graphically. The rate of heat transfer and the mass transfer at the plate has been obtained and also discussed.
