Abstract


In this paper, we have consider the radiation and hall current effects on unsteady MHD free convection flow of a viscous incompressible electrically conducting fluid past an inclined parabolic accelerated plate in a porous medium by applying a transverse magnetic field which makes an angle (α) to the inclined plate. The fluid is assumed to be viscous, incompressible and electrically conducting with a strong magnetic field. Using the modified Ohm’s law and the Bossinesq approximation the governing equations of the problem are reduced to local non-similarity boundary layer equations using suitable transformation. The dimensionless governing equations of flow field are solved numerically by a closed analytical method for various different parameters of governing flow equations. The velocity, temperature, skin-friction and Nusselt number are shown graphically and discussed qualitatively.
