摘要

The flow of a viscous fluid induced by the rotation of a disk bounded by a porous medium fully saturated with the liquid is discussed. It is assumed that the flow between the disk and the porous medium is governed by Navier-Stokes equations and that in the porous medium by Brinkman (1947) equations. Flows in the two regions are matched at the interface by the conditions suggested by Ochao-Tapia and Whittaker (1995a; b). Analytical expressions for velocity and skin-friction are obtained and discussed.
