• GALERKIN FINITE ELEMENT SOLUTION OF MHD FREE CONVECTION RADIATIVE FLOW PAST AN INFINITE VERTICAL POROUS PLATE WITH CHEMICAL REACTION AND HALL CURRENT

Abstract

Chemical reaction and radiation effects on an unsteady free convection flow of an electrically conducting gray gas near equilibrium in the optically thin limit along an infinite vertical porous plate are investigated in the presence of strong transverse magnetic field imposed perpendicularly to the plate, taking hall currents in to account.  The similarly equations were obtained using suitable transformations and the resulting non – linear coupled partial differential equations are solved by Galerkin finite element method. A parametric study illustrating the influence of different flow parameters on velocity, temperature and concentration fields are investigated. The skin – frictions at the plate due to the primary and secondary velocity fields and the rate of heat and mass transfer co – efficient are obtained in  non – dimensional form. The effects of different flow parameters on these respective fields are discussed through graphs and tables and results are physically interpreted.
