A new wrinkle on liquid sheets: Turning the mechanism of viscous bubble collapse upside down
Abstract
The collapse of viscous bubbles is of practical interest to geophysics, glass manufacturing, and food processing. Previous studies have suggested that gravity or small punctures may play a role in the wrinkling and collapse of viscous bubbles. By studying bubbles with a range of viscosity and by tilting them both sideways and upside down, Oratis et al. conclude that gravity is not a factor. Instead, surface tension and dynamic stress of the compressed liquid seem to be the main driving mechanisms for the behavior of the bubbles and the wrinkling instability.
