Combined heat and mass transfer by laminar mixed convection flow from a vertical surface with induced magnetic field

Abstract

The mixed convection flow over a continuously moving porous vertical plate under the combined buoyancy effects of thermal and mass diffusion has been studied under the action of transverse applied magnetic field taking into account the induced magnetic field, when the plate is subjected to constant heat and mass fluxes. Solutions for the velocity field, temperature distribution, concentration distribution, induced magnetic field and current density are obtained using perturbation technique. Expressions for shear stress, Nusselt number and Sherwood number are also obtained. Its apparent that the effect of Grashof number (Gr) on temperature distribution is significantly greater than the magnetic parameter and Schmidt number and the temperature distribution remains more for Gr<0 than that of Gr>0 for both air and water. It is found that the shear stress decreases with increasing Prandtl number (Pr).
