Laminar Flow Between Porous Disks

Abstract

The equation of motion for steady, incompressible, axially symmetric flow between parallel porous disks have been solved. The flow is entirely the result of either suction or injection through the disks. The solution is obtained by perturbing the creeping-flow solution. It is valid for small suction or injection Reynolds numbers. Expressions for the velocity, pressure, and shear stress are presented and compared with the creeping-flow expressions.
