• RADIATION EFFECT ON HYDROMAGNETIC CONVECTIVE FLOW OF VISCOUS LIQUID PAST AN INFINITE VERTICAL PLATE IN THE PRESENCE OF A HEAT SOURCE

SATYABHAN H SING, N. K. VARSHNEY*

Abstract


A study of radiation effect on free convection flow of an incompressible, electrically conducting, viscous liquid through time dependent porous medium past an infinite, isothermal, vertical, porous  plate is presented. A constant heat source is considered in the flow region in the presence of transversely applied uniform magnetic field and a time dependent suction velocity. To obtain the analytical solutions of velocity field and temperature field, perturbation technique is used. The expressions for skin friction and rate of heat transfer are also obtained. The effect of Magnetic parameter, Permeability parameter, Grashof number, Radiation Parameter on velocity and temperature is discussed graphically. In this study velocity of liquid increases with the increase in Gr (Grashof number), ko (Permeability parameter) and N (Radiation parameter), but it decreases with the increase in M (Magnetic parameter).
