Thermodynamic effect of single bubble near a rigid wall
Ultrasonics Sonochemistry, 2021 The objective of this paper is to numerically investigate the thermodynamic effect during bubble collapse near a rigid boundary. A compressible fluid model is introduced to accurately capture the transient process of bubble shapes and temperature, as ...

A numerical model for cloud cavitation based on bubble cluster
Theoretical and Applied Mechanics Letters, 2017 The cavitation cloud of different internal structures results in different collapse pressures owing to the interaction among bubbles. The internal structure of cloud cavitation is required to accurately predict collapse pressure.

Numerical investigation of two-microbubble collapse and cell deformation in an ultrasonic field
Ultrasonics Sonochemistry, 2023 Two-microbubble collapse near a spherical cell in an ultrasonic field is numerically analyzed by extending a level-set method for compressible multiphase flows with bubble and cell multiple interfaces.

Jets from collapsing bubbles [PDF]
Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1999 When an asymmetric bubble collapses it generally produces a well defined high velocity jet. This is remarkable because one might expect such a collapse to produce a complex or chaotic flow rather than an ordered one. I present a dimensional argument for the ubiquity of jets from collapsing bubbles, and model the aspherical collapse of a bubble with ...

Non-spherical collapse of an air bubble subjected to a lithotripter pulse [PDF]
, 2008 In order to better understand the contribution of bubble collapse to stone comminution in shockwave lithotripsy, the shockinduced and Rayleigh collapse of a spherical air bubble is investigated using numerical simulations, and the free-field collapse ...

Journal of Fluid Science and Technology, 2011 Cavitation often involves an abrupt phase change phenomenon. This phenomenon causes cavitation erosion on the material surface. In particular, violent bubble collapse near the material surface causes severe erosion.

Collapsing sub-critical bubbles [PDF]
Physics Letters B, 1992 In the standard scenario, the electroweak phase transition is a first order phase transition which completes by the nucleation of critical bubbles. Recently, there has been speculation that the standard picture of the electroweak phase transition is incorrect.

Scaling laws for jets of single cavitation bubbles [PDF]
, 2016 Fast liquid jets, called micro-jets, are produced within cavitation bubbles experiencing an aspherical collapse. Here we review micro-jets of different origins, scales and appearances, and propose a unified framework to describe their dynamics by using ...

Experimental study of laser-induced bubble collapse near a rigid wall based on the double-exposure method [PDF]
International Journal of Fluid EngineeringCapturing and studying the process of cavitation bubble collapse can help elucidate the mechanism of cavitation erosion. In this paper, a high-spatiotemporal-resolution double-exposure photographic method is used to investigate the collapse of laser ...

Differential criterion of a bubble collapse in viscous liquids [PDF]
, 1999 The present work is devoted to a model of bubble collapse in a Newtonian viscous liquid caused by an initial bubble wall motion. The obtained bubble dynamics described by an analytic solution significantly depends on the liquid and bubble parameters. The
