ABSTRACT

The unsteady MHD heat and mass transfer flow past a moving semi-infinite vertical porous plate with thermal diffusion has been investigated numerically taking into account the induced magnetic field. The steady-state numerical solutions for the velocity field, induced magnetic field, temperature distribution and concentration distribution are obtained by the explicit finite difference method. The local and average shear stress, current density, Nusselt number as well as Sherwood number are also calculated. The obtained results have been shown graphically. Also the stability and convergence of the explicit finite difference scheme are established. Finally, the comparison of the present results with both analytical and numerical solutions is presented in tabular form.

Keywords: MHD, Thermal Diffusion, Induced Magnetic Field, Finite Difference Method.
