CHEMICAL REACTION AND DUFOUR EFFECTS ON A STEADY MHD FLOW OVER A VERTICAL POROUS PLATE WITH OHMIC HEATING, VISCOUS DISSIPATION, RADIATION, HALL CURRENT AND HEAT SOURCE

The present study deals with the analysis of steady MHD flow of an incompressible electrically conducting viscous fluid through a vertical porous plate with ohmic heating, viscous dissipation, radiation, hall current and heat source in presence of chemical reaction and Dufour effect. The governing non-linear partial differential equations are transformed into a set of coupled ordinary differential equations which are then solved analytically by using regular perturbation techniques. The effect of various parameters like Schmidt number (Sc), Prandtl number (Pr), Grashof number (Gr), Modified Grashof number (Gm), Magnetic parameter (M), Radiation parameter (F), Porosity parameter (K), Hall parameter(m), Heat Source parameter (S), Chemical reaction parameter (R) and Dufour number (Du) on velocity, temperature and concentration profiles are discussed with the help of numerical values and the graphs
