Résumé

The momentum balance at the interface between a liquid and a porous substrate was investigated for a configuration with forced flow parallel to the interface. An heterogeneous continuously varying transition layer between the two outer bulk regions was introduced. The stress jump coefficient earlier introduced in the jump interface condition was derived as an explicit function of the variations in the velocity and effective properties of the transition layer. Agreement was found between the numerical results based on the single-domain approach and the existing ad hoc estimates in the literature. Further advantages of this non-homogeneous analysis are also provided.
