In the past decades, there was considerable controversy over the Lucas–Washburn (LW)
equation widely applied in capillary imbibition kinetics. Many experimental results showed …

Spontaneous imbibition is a natural phenomenon in porous media extensively occurring in
many fields of engineering applications and natural sciences. Thus, the issues on the basic …

Paper is a material known to everybody. It has a network structure consisting of wood fibres
that can be mimicked by cooking a portion of spaghetti and pouring it on a plate, to form a …

This volume chronicles the proceedings of the Third International Symposium on Contact
Angle, Wettability and Adhesion held in Providence, Rhode Island, May 20a 23, 2002. This …

The physics of liquids in porous media gives rise to many interesting phenomena, including
imbibition where a viscous fluid displaces a less viscous one. Here we discuss the …

We study experimentally how wettability impacts fluid-fluid-displacement patterns in granular
media. We inject a low-viscosity fluid (air) into a thin bed of glass beads initially saturated …

A new color‐gradient lattice Boltzmann model is developed to simulate spontaneous
imbibition in a porous media micromodel, which needs only two‐dimensional computational …

Existing continuum models of multiphase flow in porous media are unable to explain why
preferential flow (fingering) occurs during infiltration into homogeneous, dry soil. Following a …

We elaborate on the impact of liquids upon the mechanical properties of granular materials.
We find that most of the experimental and simulation results may be accounted for by a …

We present a phase field model of infiltration that explains the formation of gravity fingers
during water infiltration in soil. The model is an extension of the traditional Richards …
