MHD heat and mass diffusion flow by natural convection past a surface embedded in a porous medium

R. C. Chaudhary, Arpita Jain

This paper presents an analytical study of the transient hydromagnetic natural convection flow past a vertical plate embedded in a porous medium, taking account of the presence of mass diffusion and fluctuating temperature about time at the plate. The governing equations are solved in closed form by the Laplace-transform technique. The results are obtained for temperature, velocity, penetration distance, Nusselt number and skin-friction. The effects of various parameters are discussed on the fow variables and presented by graphs.
