Anomalous transport in porous media IV: Immiscible displacement in the diffusive limit — •Oliver Hönig1, Florian Doster1, and Rudolf Hilfer1,2 — 1Institut für Computerphysik, Universität Stuttgart, 70569 Stuttgart, Deutschland — 2Institut für Physik, Universität Mainz, 55099 Mainz, Deutschland
We study anomalous capillary diffusion in porous media. Capillary diffusion arises during macroscopic multiphase flow when capillary forces become dominant. We extend recent results on a generalised fractional flow formulation [1] into the diffusive limit.
