Three-dimensional free convection MHD flow in a vertical channel through a porous medium with heat source and chemical reaction

An analysis is made to study the three-dimensional MHD free convection flow in a vertical channel through a porous medium with heat source and chemical reaction. The flow phenomenon is characterized by magnetic parameters (M), Darcy number (K _p ), Reynolds number (R _e ), source parameter (S), Grashof number for heat transfer (G _r ), Grashof number for mass transfer (G _c ), Prandtl number (P _r ), Schmidt number (S _c ), and chemical reaction parameter (K _c ). Approximate solutions of the velocity, temperature, and concentration are obtained using a perturbation technique. The effect of these parameters on the velocity, temperature and concentrations distribution is discussed and some interesting results are presented.
