How do growing bacterial colonies get their shapes? While colony morphogenesis is well
studied in two dimensions, many bacteria grow as large colonies in three-dimensional (3D) …

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 …

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 …

Spontaneous imbibition happens in many natural and chemical engineering processes in
which the mean advancing front usually follows Lucas-Washburn's law. However it has been …

We investigate spontaneous dynamic capillary rises of liquids. While the liquid front rises
spontaneously and vertically in a capillary, hydrostatic effects become more and more …

Spontaneous imbibition plays an important role in many subsurface and industrial
applications. Unveiling pore‐scale wetting dynamics, and particularly its upscaling to the …

Spontaneous capillary imbibition is a classical problem in interfacial fluid dynamics with a
broad range of applications, from microfluidics to agriculture. Here we study the duration of …

Imbibition of water and silicone oil in poplar and spruce is investigated at the anatomical
level by X-ray tomography observations and at the macroscopic level by imbibition kinetics …

Spontaneous imbibition—the process of a wetting fluid displacing a nonwetting fluid purely
by capillary forces—is a ubiquitous phenomenon in porous and fibrous materials. Here we …

We study the behavior of an ink-paper interface in a spontaneous imbibition experiment as a
function of time and paper orientation. To characterize the interface roughness the growth β …
