Fluid flow in porous media encompasses a diverse range of phenomena that are critical to understanding processes such as groundwater transport, oil recovery, and subsurface pollutant dispersion.

Viscous fingering occurs in porous media where fluids of differing viscosity converge in finger-shaped patterns as a result of growing disturbances at the interface. Such instabilities are encountered ...

Fluid flow in porous media is a subject of considerable scientific and engineering interest, as it underpins a wide range of natural and industrial processes – from groundwater movement and oil ...
