Inferring pore connectivity from sorption hysteresis in multiscale porous media

Trapping and hysteresis in two-phase flow in porous media: A pore-network study

[1] Several models for two-phase flow in porous media identify trapping and connectivity of fluids as an important contribution to macroscale hysteresis. This is especially true for hysteresis in relative permeabilities. The trapping models propose trajectories from the initial saturation to the end saturation in various ways and are often based on experiments or pore-network model results for ...

Modeling Hysteresis in Porous Media Flow via Relaxation

Hysteresis models and gravity fingering in porous media

We study flow problems in unsaturated porous media. Our main interest is the gravity driven penetration of a dry material, a situation in which fingering effects can be observed experimentally and numerically. The flow is described by either a Richards or a two-phase model. The important modelling aspect regards the capillary pressure relation which can include static hysteresis and dynamic cor...
