Effect of rotation on the flow past a porous plate with timedependent free stream
Abstract
The effect of rotation on the unsteady flow past a porous infinite plate due to impulsive or accelerated change in the free stream has been studied as particular cases of a general problem. It is found that in the case of impulsive change in the free stream, the shear stress components at the plate for large time increase with increase in rotation parameter. Further, the shear stress components attain steady value through inertial oscillations. The steady state flow is confined within an Ekman layer the thickness of which increases with increase in either suction parameter or rotation parameter. It is also found that in the case of accelerated change in the freestream velocity, the shear stress components increase with increase in time.
