TLDR
In this article, the authors considered the flow streaming into a porous and permeable medium with arbitrary but smooth wall surface and considered the Euler equation (in the pure fluid region) and generalized Darcy's law in which the convective acceleration is taken into account.Abstract:
The flow streaming into a porous and permeable medium with arbitrary but smooth wall surface is considered on the basis of the Euler equation (in the pure fluid region) and a generalized Darcy's law in which the convective acceleration is taken into account. The asymptotic behavior of the flow for small permeability of the medium is investigated. It is shown that the flow in the porous medium is irrotational except in the boundary layer next to the surface. The velocity distribution in the boundary layer is given in a universal form. Proper boundary conditions connecting the potential flow in the pure fluid region and the potential flow in the porous medium are obtained when the boundary layer is neglected.read more

TL;DR: The analysis showed that transport phenomena are strongly dependent on the phase shift between the two walls of the channel, and it is indicated that the axial velocity component U in fixed frame increases with increasing the permeability parameter.

Flow and Diffusion of Gases in Porous Media
TL;DR: A generalized treatment of gas transport in porous media is presented as developed on the basis of the ''dusty gas'' model, a model in which a porous medium is described as consisting of uniformly distributed, giant molecules (dust) held stationary in space as mentioned in this paper.
