Lamella Thinning Laws - Fundamental Building Blocks in Foam Dynamics

Capillary pressure drives the liquid in foam films (lamellae) into the adjacent film junctions (Plateau borders), resulting in the thinning and eventual rupture of the films. These thinning processes obey scaling laws, which are found using asymptotic methods and boundary integral simulations. Three idealized arrangements are considered: a Plateau border joining (1) two free films, (2) a free film and a bounded film, (3) two bounded films.
