TLDR
In this article, a volume-of-fluid-based finite volume method was developed for simulating two-phase flow directly on micro-CT images of porous media and an analytical analysis of the relationship between the pore-scale forces and the Darcy-scale pressure drops was presented.About:

Generalized network modeling: Network extraction as a coarse-scale discretization of the void space of porous media.
TL;DR: A generalized network extraction workflow is developed for parameterizing three-dimensional (3D) images of porous media and it is shown that the network extraction preserves macroscopic properties, the permeability and formation factor, and the statistics of the micro-CT images.

TL;DR: It is shown that the time-scales of interface movement and brine layer swelling leading to snap-off are several minutes, orders of magnitude slower than observed for Haines jumps in drainage, and the local capillary pressure increases rapidly aftersnap-off as the trapped phase finds a position that is a new local energy minimum.

A continuum method for modeling surface tension
TL;DR: In this paper, a force density proportional to the surface curvature of constant color is defined at each point in the transition region; this force-density is normalized in such a way that the conventional description of surface tension on an interface is recovered when the ratio of local transition-reion thickness to local curvature radius approaches zero.

TL;DR: The Navier-Stokes equations can be employed for useful practical applications beyond the elementary problems of laminar flow in pipes and Stokes law for the motion of a single particle as mentioned in this paper.

TL;DR: Pore-scale imaging and modelling is becoming a routine service in the oil and gas industry as discussed by the authors, and has potential applications in contaminant transport and carbon dioxide storage, which has been shown to transform our understanding of multiphase flow processes.
