Hydromagnetic heat and mass transfer flow with time dependent suction and porous medium in rotating system

Abstract

In the present paper free convection and mass transfer effects in the unsteady flow of an incompressible, electrically conducting, viscous liquid in a porous medium past an infinite porous vertical plate with time dependent suction in a rotating system in the presence of uniform magnetic field applied perpendicular to the flow region is studied. The effects of magnetic parameter, rotation parameter, Grashof number, heat source parameter, Prandtl number, permeability parameter, modified Grashof number and Schmidt number or primary velocity and secondary velocity for cooling case and the effects of the above stated parameters on primary velocity and secondary velocity for cooling case and the effects of the above stated parameters on primary velocity and secondary velocity for heating case are discussed with the help of graphs while the effects of these parameters on skin-friction are discussed with the help of graphs while the effects of these parameters on skin­-friction are discussed with the help of tables. The rate of heat transfer and the rate of mass transfer are also discussed with the help of tables.
