Unsteady MHD Flow in a Rotating Parallel Plate Channel under the Influence of Pressure Gradient with Hall Current Effects

In this paper we discussed the unsteady flow of an incompressible electrically conducting viscous fluid in a rotating porous media, with a variable pressure gradient and in the presence of hall current. We have considered three different cases, like impulsive change, cosine and sine oscillations of pressure gradient. It is found that, the rotational and Lorentz forces are having significant effect on velocity profile in the presence of pressure gradient and hall current. The physical significance of various dimensionless parameter’s are discussed analytically and numerically on velocity distribution and frictional force.
