UNSTEADY FLOW OF VISCOUS FLUID THROUGH A POROUS MEDIUM BOUNDED BY A POROUS PLATE IN A ROTATING SYSTEM

The flow of an unsteady viscous incompressible fluid past an infinite porous plate embedded in a porous medium in a rotating system has been studied. An analytical solution describing the flow at small and large times is obtained by the Laplace transform technique. It is observed that the velocity components increase with increase in porosity parameter. It is also found that for small values of time, there are no inertial oscillations, while for large values of time, the fluid reaches the steady state through inertial oscillations. Furthermore, the inertial oscillations are unaffected by both the suction/blowing and the permeability of the porous medium while it is affected by the rotation parameter.
