Abstract

Local flow in the boundary layer in the vicinity of a porous wall is investigated. On the basis of asymptotical analysis, mathematical models are formulated and similarity parameters are determined. Numerical and analytical results describing the interaction of laminar flows near a porous wall with external flow for the case when pressure under the wall exceeds the disturbed pressure over the wall are presented. The pressure drop regimes are investigated.
