In soil chemistry or marine microbiology (for example when dealing with marine aggregates), one often encounters situations where porous bodies are suspended in a fluid. In this context, the question of boundary conditions for the fluid velocity and pressure at the porous-liquid interface arises. Up to the present, only results for straight interfaces are known.

In this project, the behaviour of a free fluid above a porous medium is investigated, where the interface between the two flow regions is assumed to be curved.
