Abstract
Predicted capillary pressure curves are consistent with experimental data presented in the literature. This provides strong (though indirect) support for the physically consistent dynamic criterion for the imbibition of a single pore. We illustrate two important and non-trivial consequences of the criterion that also agree with experiments: its implications when wettability (value of contact angle) of the medium varies, and its consistency with the Mayer-Stowe-Princen criterion for drainage at the level of individual pores. We then explore novel features of the criterion. For example, the percolation threshold for imbibition is a manifestation of two kinds of accessibility of the wetting phase, rather than one. Another feature is the strong coupling between the criterion and the spatial correlation of pore-level geometric features, which significantly affects the topology and connectivity of the wetting phase.
