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

摘要

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 (Kp), Reynolds number (Re), source parameter (S), Grashof number for heat transfer (Gr), Grashof number for mass transfer (Gc), Prandtl number (Pr), Schmidt number (Sc), and chemical reaction parameter (Kc). 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.
