Numerical simulations of non-spherical bubble collapse [PDF]
Journal of Fluid Mechanics, 2009 A high-order accurate shock- and interface-capturing scheme is used to simulate the collapse of a gas bubble in water. In order to better understand the damage caused by collapsing bubbles, the dynamics of the shock-induced and Rayleigh collapse of a bubble near a planar rigid surface and in a free field are analysed.

Collapse of vacuum bubbles in a vacuum [PDF]
Physical Review D, 2011 Motivated by the discovery of a plenitude of metastable vacua in a string landscape and the possibility of rapid tunneling between these vacua, we revisit the dynamics of a false vacuum bubble in a background de Sitter spacetime. We find that there exists a large parameter space that allows the bubble to collapse into a black hole or to form a wormhole.

The enhanced effect of collapse strength of a dual-frequency driven bubble in 2-dimensional space
Results in Physics, 2021 The bubble-collapse strength is closely related to the ultrasonic cavitation effect. The enhanced effect of collapse strength of a dual-frequency driven bubble is one of the mechanisms underlying the synergistic effect of dual-frequency excitation.

Multibubble Sonoluminescence from a Theoretical Perspective
Molecules, 2021 In the present review, complexity in multibubble sonoluminescence (MBSL) is discussed. At relatively low ultrasonic frequency, a cavitation bubble is filled mostly with water vapor at relatively high acoustic amplitude which results in OH-line emission ...

Collapse of Kaluza-Klein bubbles [PDF]
Physical Review D, 1994 Kaluza-Klein theory admits ``bubble" configurations, in which the circumference of the fifth dimension shrinks to zero on some compact surface. A three parameter family of such bubble initial data at a moment of time-symmetry (some including a magnetic field) has been found by Brill and Horowitz, generalizing the (zero-energy) ``Witten bubble" solution.

Energies, 2022 The collapse of a cavitation bubble is always associated with the radiation of intense shock waves, which are highly relevant in a variety of applications.

Ultrasonics Sonochemistry, 2021 Cavitation damage is a micro, high-speed, multi-phase complex phenomenon caused by the near-wall bubble group collapse. The current numerical simulation method of cavitation mainly focuses on the collapse impact of a single cavitation bubble.
