Abstract:

The boundary region between an open viscous flow and a porous matrix has been examined for parallel flow by numerical solution of the viscous flow equations. Results for simple shear flow are consistent with analytic theory and experimental results on a slotted diskRichardson-Taylor model. Results for pressure-driven flow are new. The variation of the slip velocity at the boundary plane with geometric parameters is illustrated, and its prediction via slip coefficients is discussed.
