Underground hydrogen storage (UHS) is a promising technology with which large quantities
of H 2 can potentially be stored in the subsurface safely, economically and efficiently. As …

Finger-like protrusions that form along fluid− fluid displacement fronts in porous media are
often excited by hydrodynamic instability when low-viscosity fluids displace high-viscosity …

Carbon dioxide and hydrogen storage in geological formations at Gt scale are two promising
strategies toward net-zero carbon emissions. To date, investigations into underground …

Hydrogen has become increasingly popular as one of the alternative fuels to reduce
greenhouse gas emissions. Storing hydrogen in geological structures is a technology that …

Flow and transport through fractured geologic media often leads to anomalous (non‐
Fickian) transport behavior, the origin of which remains a matter of debate: whether it arises …

The coupling between solute transport and rock's geomechanical processes, for example,
flow‐induced fracture activation, has emerged as an important hydrogeological challenge …

Fluid mixing plays a fundamental role in many natural and engineered processes, including
groundwater flows in porous media, enhanced oil recovery, and microfluidic lab‐on‐a‐chip …

The dynamics of the interface of liquids with a high viscosity contrast, performing harmonic
oscillations with zero mean in a straight slot channel, is experimentally investigated. The …

Geologic carbon storage (GCS) is a promising method for reducing anthropogenic CO 2
emissions to the atmosphere. To safely deploy GCS in the field, it is necessary to assess …

We investigate the coupled dynamics of fluid mixing and viscously unstable flow under both
miscible (single‐phase) and partially miscible (two‐phase) conditions, and in both …
