A homogenization approach is proposed for the treatment of porous wall boundary conditions in computation compressible viscous flows. Like any other approach, it eliminates need pore-resolved fluid meshes, and therefore enables practical flow simulations computational domains with boundaries. Unlike alternative approaches, however, does not require prescribing a mass rate introduce model heuris...
