Breakup of Air Bubbles in Water: Memory and Breakdown of Cylindrical Symmetry
arXiv:cond-mat/0605669 · doi:10.1103/PhysRevLett.97.144503
Abstract
Using high-speed video, we have studied air bubbles detaching from an underwater nozzle. As a bubble distorts, it forms a thin neck which develops a singular shape as it pinches off. As in other singularities, the minimum neck radius scales with the time until breakup. However, because the air-water interfacial tension does not drive breakup, even small initial cylindrical asymmetries are preserved throughout the collapse. This novel, non-universal singularity retains a memory of the nozzle shape, size and tilt angle. In the last stages, the air appears to tear instead of pinch.
