EFFECT OF ROTATION AND THERMAL RADIATION ON MHD CONVECTIVE FLOW ALONG AN INFINITE VERTICAL POROUS PLATE WITH VARIABLE SUCTION AND HEAT ABSORPTION

Abstract

This paper deals with the study of the rotation and thermal radiation effects on MHD convective flow along an infinite vertical porous plate in presence of Hall current with variable suction and heat generation in a porous medium. A magnetic field of uniform strength is assumed to be applied in a direction normal to the porous plat . The equations governing the fluid flow are solved using the perturbation technique and the expressions for the velocity, the temperature and the concentration distributions have been obtained. Dimensionless velocity, temperature and concentration profiles are displayed graphically for different values of the parameters entering into the problem like Prandtl number(Pr),Hartmann number(M), Grashof number(Gr), ^{modified Grashof number(Gc),Hall parameter (m), Heat source parameter}  ^{Schmidt number (Sc), rotation  ,} porous medium k₁ and thermal radiation . The profiles of the skin friction coefficient , rate of heat transfer and

mass transfer at the plate are demonstrated graphically for various values of the physical parameters involved in the problem and the result are physically interpreted.
