Filtration-Flow Fragmentation in Medium with Capillary-Pressure Gradient

Аннотация

The deformation of a water-saturated region during filtration in a porous medium with variable capillary pressure is considered. The numerical calculations show that the capillary-pressure gradient directed along the liquid-gas interface leads to deformation of the region, which is eventually divided into two disconnected regions. It is assumed that the process under consideration describes one of the possible mechanisms of fragmentation of filtration flows.
