Birth and growth of cavitation bubbles within water under tension confined in a simple synthetic tree [PDF]
, 2012 Water under tension, as can be found in several systems including tree vessels, is metastable. Cavitation can spontaneously occur, nucleating a bubble. We investigate the dynamics of spon- taneous or triggered cavitation inside water filled microcavities

Cavitation inception from bubble nuclei [PDF]
Interface Focus, 2015 The tensile strength of ordinary water such as tap water or seawater is typically well below 1 bar. It is governed by cavitation nuclei in the water, not by the tensile strength of the water itself, which is extremely high. Different models of the nuclei have been suggested over the years, and experimental investigations of bubbles and cavitation ...

Onset of cavitation in the quark-gluon plasma [PDF]
, 2014 We study the onset of bubble formation (cavitation) in the quark-gluon plasma as a result of the reduction of the effective pressure from bulk-viscous corrections.

A bubble fission model for collapsing cavitation bubbles
Physics of Fluids, 2004 A bubble fission model that takes into account energy dissipation during violent collapses of cavitation bubbles is introduced by assuming volume conservation and continuity of the gas pressure during instantaneous breakup, invoking either Rayleigh–Taylor instability or high speed microjet formation.

Single-bubble and multi-bubble cavitation in water triggered by laser-driven focusing shock waves
, 2018 In this study a single laser pulse spatially shaped into a ring is focused into a thin water layer, creating an annular cavitation bubble and cylindrical shock waves: an outer shock that diverges away from the excitation laser ring and an inner shock ...

Particle Motion Induced by Bubble Cavitation
Physical Review Letters, 2015 Cavitation bubbles induce impulsive forces on surrounding substrates, particles, or surfaces. Even though cavitation is a traditional topic in fluid mechanics, current understanding and studies do not capture the effect of cavitation on suspended objects in fluids.

On the gas pressure inside cavitation bubbles
Physics of Fluids, 2023 The validity of the reduced order [Delale and Pasinlioglu, “Acoustic cavitation model based on a novel reduced order gas pressure law,” AIP Adv. 11, 115309 (2021)] and of classical polytropic gas pressure laws during the response of a bubble to variations in the pressure of the surrounding liquid is investigated.

Observations and scaling of travelling bubble cavitation [PDF]
, 1995 Recent observations of growing and collapsing bubbles in flows over axisymmetric headforms have revealed the complexity of the ‘micro-fluid-mechanics’ associated with these bubbles (van der Meulen & van Renesse 1989; Briancon-Marjollet et al.

Multibubble cavitation inception
, 2009 The inception of cavitation in multibubble cases is studied numerically and theoretically to show that it is different from that in single-bubble cases in several aspects.

Cavitation in linear bubbles [PDF]
Journal of Fluid Mechanics, 2009 Recent work has developed a beautiful model system for studying the energy focusing and heating power of collapsing bubbles. The bubble is effectively one-dimensional and the collapse and heating can be quantitatively measured. Thermal effects are shown to play an essential role in the time-dependent dynamics.
