Unsteady Stokes Flow of Viscous Fluid between Two Parallel Porous Plates

Abstract

Berman(1953) was the first researcher who studied the problem of steady flow of an incompressible viscous fluid through a porous channel with rectangular crosssection, when the Reynolds number is low. He obtained a perturbation solution assuming normal wall velocities to be equal. Then Sellars(1955) extended the problem studied by Berman when the Reynolds number is very high. Afterwards Yuan(1956) and Terill(1964) studied the problem for various values of suction and injection Reynolds numbers. Terill and Shrestha(1965) have analysed the same problem, assuming different normal velocities at the walls.
