Effect Of Chemical Reaction On Velocity Of Mhd Flow Of A Viscous Conducting Fluid In A Porous Channel

This paper presents an analytical method of solution to Hall effect on hydromagnetic free convection flow in a vertical porous channel with mass transfer and chemical reaction. The exact solutions of equations of motion, heat transfer and mass transfer are obtained by complex variable technique. The expressions for primary velocity and secondary velocity are also derived. The variations in fluid velocity are displayed graphically. Primary velocity rises with increase in the Schmidt number (S-c),permeability parameter (K-1*) and modified Grashof number for mass diffusion (G(c)) ,but remains unaffected with increase in reaction rate constant (R*).The secondary velocity rises with increase in Reynolds number (R) and mass diffusion Grashof number but falls with increase in Reaction rate constant and permeability parameter
