A new wrinkle on liquid sheets: Turning the mechanism of viscous bubble collapse upside down – Science Magazine
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 bub…
Abstract
Viscous bubbles are prevalent in both natural and industrial settings. Their rupture and collapse may be accompanied by features typically associated with elastic sheets, including the development of radial wrinkles. Previous investigators concluded that the film weight is responsible for both the film collapse and wrinkling instability. Conversely, we show here experimentally that gravity plays a negligible role: The same collapse and wrinkling arise independently of the bubbles orien…
