We determined the self-diffusion coefficients of hydrogen in clay (montmorillonite)
nanopores using molecular dynamics under subsurface conditions. We explored the effects …

In order to elucidate the oil displacement mechanism of micro-emulsions formed by different
betaines at pore throats, this study selected three betaine surfactants with different …

Combined with strengths of water and CO 2 flooding, water-alternating-CO 2 (WAG)
injection stabilizes displacement front and suppresses viscous fingering. Optimal injection …

Multiphase flow is a common scenario in industrial and environmental applications.
Especially at microscopic scale, accurately describing flow processes is challenging due to …

Gas-liquid displacement in porous media widely exists in many terrestrial/extraterrestrial
subsurface resource extraction and utilization applications. The typical fingering …

Injecting supercritical CO 2 into tight gas reservoirs to displace CH 4 is an extremely
promising technology of unconventional gas exploitation. However, Darcy's law cannot …

This work examines a type of rapid pore-filling event in multiphase flow through permeable
media that is better known as Haines Jump. While existing microfluidic experiments on …

Various types of micro/nano functional devices are being widely designed as optical
switches, micro scanners, micromirrors and other core optical devices. The continuing …

This work introduces Fronts, a set of open-source numerical software packages for nonlinear
horizontal capillary-driven flow problems in unsaturated porous media governed by the …

In different industries and environments, water-in-oil emulsions are complicated mixtures of
multiple phases. They are useful for enhanced oil recovery, petroleum refining, and oil spill …
