Underground hydrogen storage (UHS) has been launched as a catalyst to the low-carbon
energy transitions. The limited understanding of the subsurface processes is a major …

Long-term and large-scale H 2 storage is vital for a sustainable H 2 economy. Research in
underground H 2 storage (UHS) in porous media is emerging, but the understanding of H 2 …

Surface wettability is one of the major factors that regulate immiscible fluid displacement in
porous media. However, the role of pore-scale wettability heterogeneity on dynamic …

Drainage displacement at unfavorable viscosity ratios is often encountered in oil recovery,
CO2 sequestration, and NAPL remediation, which significantly limits recovery of fluids from …

Roughness and wettability of the fracture surface have crucial effects on the two-phase flow
properties in many applications involving fractured rock. The immiscible quasi-static …

Understanding transport phenomena and governing mechanisms of different physical and
chemical processes in porous media has been a critical research area for decades …

Snap‐off is a phenomenon that occurs when a non‐wetting fluid is displaced by wetting fluid
in pore‐throat channels, leading to the breakup of droplets at the throat. Snap‐off plays a …

The flow of multiple immiscible fluids in disordered porous media is important in many
natural processes and subsurface applications. The pore‐scale disorder affects the fluid …
