Abstract:
Wet foams are random-close-packed assemblies of approximately spherical gas bubbles in a liquid. We report rheological experiments with this material, showing that even though the stiffness and frictional interactions of bubbles strongly distinguish them from solid spherical grains, jamming and flow of wet foams and granular materials are governed by closely analogous laws.

Capillarity in Fluid
Surface tension is crucial to capillarity. It results from cohesive forces between liquid molecules at the liquid-air boundary, forming a skin that resists external forces. When the capillary tube...
