Marginal regeneration in a horizontal film: Instability growth law in the nonlinear regime
Alice Gros, Adrien Bussonnière, Sanjiban Nath, Isabelle Cantat
Abstract
The marginal regeneration process responsible for foam film drainage is revisited. It is shown that a horizontal, micron thick, foam film in contact with a meniscus destabilizes and that patches of thinner film grow along the meniscus, forming a very regular pattern.
