Self-similar and universal dynamics in drainage of mobile soap films
We experimentally investigated the drainage of vertical rectangular soap films as they thin under gravity. Drainage dynamics were measured by tracking isothickness interference fringes. We showed that the downward motion of these fringes is self-similar with a power-law time evolution, or equivalently, that the thickness profiles exhibit space-time separation. By combining our data with previous studies, we collapsed all profiles onto a single curve, demonstrating the universality of this phenomenon. These findings are important for studying liquid foams and marginal regeneration instability.
