• EFFECT OF CHEMICAL REACTION AND RADIATION ABSORPTION ON HYDRO-MAGNETIC CONVECTIVE HEAT AND MASS TRANSFER FLOW IN A NON-UNIFORMLY HEATED VERTICAL CHANNEL WITH HEAT GENERATING SOURCES
Abstract
We discuss the effect of chemical reaction and radiation absorption on free connective heat and mass transfer flow of a viscous electrically conducting fluid through a porous medium in a non-uniformly heated vertical channel .The walls are maintained at non-uniform temperature and a uniform concentration is maintained on the walls. The coupled equations governing the flow, heat and mass transfer have been solved by using a perturbation technique with the slope of the boundary temperature as a perturbation parameter. The expressions for the velocity, the temperature, concentration, the rate of heat and mass transfer are derived and these are analyzed for different variations of the governing parameters Grashof number (G), Reynolds number (R), Hartmann number (M), Heat source parameter (a), Schmidt number (Sc), Radiation absorption parameter (Q1), Buoyancy ratio (N), Chemical reaction parameter (k), Prandtl number (P) and Axial direction of the channel (x).
