Pore-scale dynamics and the multiphase Darcy law
Ying Gao, Qingyang Lin, Branko Bijeljic, Martin J. Blunt
Abstract
Time-resolved synchrotron x-ray microtomography combined with pressure measurements during two-phase displacement in porous media identifies three flow regimes. Intermittent occupancy creates temporary high-conductivity connections, leading to a power-law trend of pressure gradient with flow rate.
