Effects of Suction/Injection on Free Convective Radiative Flow In A Vertical Porous Channel With Mass Transfer And Chemical Reaction

Abstract

This paper presents an analysis of the effect of suction/injection on free convective flow past a vertical porous plate under the action of thermal radiation and chemical reaction when heat is supplied to the plate at constant rate. The governing equations are solved using implicit finite difference method. The results are obtained for the velocity, temperature, concentration, skin-friction, Nusselt number, and Sherwood number. The effects of various parameters on flow variables are illustrated physically, and the physical aspects of the problem are discussed. During the course of numerical computation, it was found that the velocity and temperature profiles increase with an increase in suction/injection parameter. Also, the skin-friction and rate of heat transfer increase with increase in radiation parameter and it shows reverse effect in the case of Sherwood number.
