Deskripsi
Porous media that display a gradient in the structure of their networks are common in nature, but the understanding of the drainage patterns in such media is still limited. We propose a theoretical framework that allows to better quantify these patterns, and we validate it both with experiments in 3D printed models and with numerical simulations.
