Relate pore-scale events to continuum-scale flow

Characterize how pore-scale interfacial events, including Haines jumps, snap-off, and ganglion coalescence, collectively determine continuum-scale multiphase flow in porous media.

Background

The paper identifies Haines jumps, snap-off, and ganglion coalescence as localized events that control trapping, phase connectivity, and hysteresis. Although these events are resolved at the pore scale, the authors state that their aggregate contribution to continuum-scale behavior remains unresolved. This problem motivates the development of physically informed data-driven models and evaluation metrics for multiphase flow in porous media.
