A Homogenization Approach for Turbulent Channel Flows over Porous Substrates: Formulation and Implementation of <i>Effective</i> Boundary Conditions

The turbulent flow through a plane channel bounded by a single permeable wall is considered; this is a problem of interest since a carefully chosen distribution of grains and voids in the porous medium can result in skin friction reduction for the flow in the channel. In the homogenization approach...
