Plateau border bulimia transition: discontinuities expected in three simple experiments on 2D liquid foams

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/219815We describe the geometry of foams squeezed between two solid plates (2D GG foams) in two main asymptotic regimes: fully dry floor tiles and dry pancakes. We predict an abrupt transition between both regimes, with a substantial change in the Plateau border radius. This should be observable in different types of experiments on such 2D GG foams: when foam is being progressively dried or wetted, when it is being squeezed further or stretched, when it coarsens through film breakage or Oswald ripening.8 pages, 4 figuresSoft Condensed MatterPlateau border bulimia transition: discontinuities expected in three simple experiments on 2D liquid foamstext
