Abstract
The aim of the present paper is to study the motion of the three-dimensional unsteady flow of an incompressible, homogeneous, viscous fluid through porous medium bounded by a porous plate with a given velocity to uniform suction or injection in a rotating system. Both the plate and the fluid are in the state of solid body rotation with constant angular velocity Ω about z-axis normal to the plate. A non-torsional oscillation of a given frequency w is super- imposed on the plate for the generation of an unsteady flow in the rotating system. An exact solution of the Navier-Stoke's equations for the unsteady flow is obtained by using the Laplace-transform technique. The effects of uniform suction, injection, permeability and magnetic field on the flow phenomenon in rotating system have also been investigated.
