CAPILLARY HYDRAULIC JUMP IN A PLATEAU BORDER

Résumé

We study transient flows of liquid along a single Plateau border (PB). In opposition with a common belief, we show that a fast, inertial regime of flow, very little dependent on the fluid viscosity, can be encountered in the high surface mobility limit. This newly observed regime evolves into the regular viscous regime after a critical distance that can be as large as several centimeters for very dry foams. The inertial regime should be observed in macroscopic experiments as a transient feature of drainage under gravity.
