THE STUDY OF MAGNETO HYDRODYNAMIC FREE CONVECTIVE FLOW AND HEAT TRANSFER IN A POROUS MEDIUM WITH HEAT GENERATION, RADIATION ABSORPTION AND CHEMICAL REACTION

Abstract

Abstract: A study for the problem of unsteady convection flow of a viscous incompressible electrically conducting micro-polar fluid in a porous medium past an inclined moving porous plate in the presence of a transverse magnetic field, heat generation, radiation absorption, chemical reaction and suction is presented. The porous plate moves with a constant velocity and the stream velocity is assumed to follow an exponentially increasing perturbation law. The porous plate absorbs the polar fluid with a suction velocity which varies with time. The dimensionless governing equations are solved analytically by perturbation technique. The numerical results are also compared with corresponding Newtonian fluid flow problems. The effects of various parameters on the velocity, micro-rotation, temperature, concentration fields, skin friction coefficient, couple stress coefficient, Nusselt number and Sherwood number are presented in graphical and tabular form.
