Momentum jump condition at the boundary between a porous medium and a homogeneous fluid: Inertial effects. (English) Zbl 0931.76094
The momentum transfer condition that applies at the boundary between a porous medium and a homogeneous fluid when inertial effects are important is developed as a jump condition based on the nonlocal form of the volume averaged momentum equation. Outside the boundary region, this non-local form reduces to the classical transport equation. The authors use a generalized momentum equation to derive the momentum flux jump condition that contains two parameters of order $$1$$, that must be determined by comparison with experiments.
