Fluent: How to model capillary driven flow in porous media model?
I want to simulate a transient two-phase flow with VOF in porous media considering capillary action. The porous zone is initially filled with air. I want to model the displacement of air with liquid water due to capillary forces. My main interest is the degree of wetting and the spreading of the wetting front. How to model capillary effects in the porous zone?
