Gas-liquid foams are important in applications ranging from oil recovery and mineral
flotation to food science and microfluidics. Beyond their practical use, they represent an …

Thin film flows, whether driven by gravity, surface tension, or the relaxation of elastic
boundaries, occur in many natural and industrial processes. Applications span problems of …

Abstract In Enhanced Geothermal System (EGS) hydraulic fracturing is carried out by
injecting cold water into deep Hot Dry Rocks (HDR) under carefully controlled conditions to …

Surface meltwater reaching the base of the Greenland Ice Sheet transits through drainage
networks, modulating the flow of the ice sheet. Dye and gas-tracing studies conducted in the …

Using gas to drive liquid from a Hele-Shaw cell leads to classical viscous fingering.
Strategies for suppressing fingering have received substantial attention. For steady injection …

The displacement of a viscous liquid by a gas within a Hele-Shaw cell is a classical problem.
The gas–liquid interface is hydrodynamically unstable, forming striking fingerlike patterns …

Foams have been used as fracking fluids for decades, but their thermodynamic instability
has always restricted subsurface applications, particularly in harsh reservoir conditions …

The intrinsic thermodynamic instability of foam systems significantly constrains their
effectiveness in enhancing oil and gas recovery from unconventional reservoirs. This study …

Surfactants and polymers are two common chemicals used to stabilize the wet foam, but
molecular-level insights into the structures, dynamics and hydrogen bonds of these agents …

Preferential flow is commonly encountered but decreases the efficiency of multiphase
displacement in most industrial processes. Microgel particle suspensions with …
