MHD Rotating Flow Through a Porous Medium with Heat and Mass Transfer

Abstract

In this paper, we have considered heat and mass transfer on the unsteady two dimensional MHD flow through porous medium under the influence of uniform transverse magnetic field in a rotating parallel plate channel. A mathematical model is developed for unsteady state situations using slip conditions. Analytical expressions for the velocity, temperature and concentration profiles, wall shear stress, rates of heat and mass transfer and volumetric flow rate have been obtained and computationally discussed with respect to the non-dimensional parameters. We concluded that the velocity reduces with increasing Hartmann number Mandenhances with permeability parameter K. Blood visco-elasticity lesser flow velocity significantly. The resultant velocity enhance with increasing Gr, Gc and slip parameter. At any particular location as the thermal radiation increases, both heat transfer rate and temperature are reduced to an appreciable extent. However, the velocity is not significantly affected by thermal radiation.
