Dynamic behavior of the cavitation bubbles collapsing between a rigid wall and an elastic wall
AIP Advances, 2021 There are various bubble cavitation phenomena in daily production and life, and near-wall cavitation is the most common one. This paper studies the bubble cavitation dynamics between a rigid wall and an elastic wall, and by changing the distance between ...

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.

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.

Radial oscillation and translational motion of a gas bubble in a micro-cavity
Ultrasonics Sonochemistry, 2022 According to classical nucleation theory, a gas nucleus can grow into a cavitation bubble when the ambient pressure is negative. Here, the growth process of a gas nucleus in a micro-cavity was simplified to two “events”, and the full confinement effect ...
