The effects of suction on the flow of an incompressible fluid past an infinite porous plate with fluctuations in the stream velocity
Abstract
An analysis of a twodimensional unsteady flow past an infinite plate has been carried out, taking into account the effects of suction and freestream oscillations. Approximate solutions to the velocity and temperature fields have been derived. It has been observed that at small values of the suction parameter gamma, there occurs a reversetype of flow when the frequency is small and increasing. But at large values of gamma, the reversetype of flow does not appear near the plate. Also, the amplitude of the skinfriction is found to increase with increasing gamma or omega. In the case of isothermal plate, greater viscous dissipative heat causes a rise in the mean temperature of the fluid and a fall in the rate of heat transfer. The mean rate of heat transfer increases with increasing gamma and decreases with increasing omega.
