To seal or not to seal: The closure dynamics of a splash curtain
Javad Eshraghi, Sunghwan Jung, Pavlos P. Vlachos
Abstract
Splashes are ubiquitous in nature and engineering, and they govern processes from diving to ocean oxygenation. Yet, to date, it is not understood when or why a splash sometimes seals and sometimes does not. Supported by theory and experimental observations, a detailed analysis is presented, and a critical dimensionless number that predicts the occurrence of a surface seal is uncovered.
