• EFFECT OF THERMAL RADIATION, RADIATION ABSORPTION ON DOUBLE DIFFUSIVE HEAT TRANSFER FLOW OF A VISCOUS CHEMICALLY REACTING FLUID IN A NON-UNIFORMLY HEATED VERTICAL CHANNEL WITH HEAT SOURCES

C. Sulochana, Ramesh H.*

Abstract


In this paper, we discuss the effect of chemical reaction and radiation absorption on free connective heat and mass transfer flow of a viscous electrically conducting fluid 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 expression for the velocity, the temperature, concentration, the rate of heat and mass transfer are derived and are analysed for different variations of the governing parameters G,R,M,a, Sc,Q1, a1, N, K, P and x.


Keywords
