Combined Effects of Hall Currents and Rotation on

Combined effects of Hall currents and rotation on MHD mixed convection in a rotating vertical channel have been studied. The governing equations are solved analytically in closed form. The effects of the various parameters on the velocity field, shear stresses, temperature field and the rate of heat transfer in terms of their amplitudes and tangent of phases are presented graphically. It is observed that the primary velocity decreases while the magnitude of the secondary velocity increases with an increase in Hall parameter parameter. It is also observed that both the primary velocity and the magnitude of the secondary velocity decrease with an increase in radiation parameter. Further, it is seen that the amplitudes of rate of heat transfer at the plates increases with an increase in either Prandtl number or radiation parameter or frequency parameter.
