摘要

The equations of motion for steady incompressible flow in an annulus with fluid removal or injection at the porous walls have been reduced to a pair of ordinary differential equations by Terrill. The solution of the related problem of a plane channel with a moving wall can be expressed in terms of the corresponding results for a stationary wall. That solution is obtained in the present work. The solution is used to determine the drag on the moving wall. Preliminary experimental results with an apparatus consisting of a porous outer cylinder and a solid rotating shaft indicate satisfactory agreement with the theoretical calculations for the case of fluid injection.
