Instability of the one-dimensional thickness profile at the edge of a horizontal foam film and its Plateau border
Corentin Trégouët, Isabelle Cantat
Abstract
The thinning of the liquid films separating bubbles in a foam or in a bubbly liquid controls the coalescence process and the foam stability, and is highly relevant in many industrial processes. This thinning process leads to films of heterogeneous thickness, in which spontaneous symmetry breaking occurs, shown to be driven by surface minimization only.
