• MAGNETIC FIELD EFFECT ON TRANSIENT FREE CONVECTION FLOW THROUGH POROUS MEDIUM PAST AN IMPULSIVELY STARTED VERTICAL PLATE WITH FLUCTUATING TEMPERATURE AND MASS DIFFUSION

Abstract

In this paper mass transfer effects on MHD, radiative free convection flow through porous medium past an impulsively started vertical plate with variable temperature and mass diffusion in presence of transverse magnetic field is investigated. The non-dimensional governing equations are solved by the usual Laplace transform technique. The effects of various physical parameters viz., radiation parameter N, Grashof number Gr, modified Grashof number Gm, Prandtl number Pr, Schmidt number Sc, time t, permeability parameter K and magnetic parameter M on velocity field, temperature field and concentration are studied through graphs. Expression for Skin friction is also derived and discussed. It is noticed that velocity decreases with an increase in M, Gm, N and Gr where as it shows reverse effect in case of K.
