MHD MIXED CONVECTION FLOW IN A ROTATING CHANNEL IN THE PRESENCE OF AN INCLINED MAGNETIC FIELD WITH THE HALL EFFECT

A numerical study of an oscillatory unsteady MHD fl ow and heat and mass transfer in a vertical rotating channel with an inclined uniform magnetic fi eld and the Hall effect is carried out. The conservation equations of momentum, energy, and species are formulated in a rotating frame of reference with inclusion of the buoyancy effects and Lorentz forces. The Lorentz forces are determined by using the generalized Ohm law with the Hall parameter taken into account. The obtained coupled partial differential equations are nondimensionalized and solved numerically by using the explicit fi nite difference method. The effects of various model parameters, like the Hall parameter, Hartmann number, wall suction/injection parameter, rotation parameter, angle of magnetic fi eld inclination, Prandtl number, Schmidt number, etc., on the channel velocities, skin friction coeffi cients, Nusselt number, and the Sherwood number are examined. It is found that the infl uence of the Hartmann number and Hall parameter on the channel velocities and skin friction coeffi cients is dependent on the value of the wall suction/injection parameter
