Impact-driven cavitation bubble dynamics
Experiments in Fluids, 2022 Abstract The dynamics of a single cavitation bubble exposed to a transient acceleration is studied experimentally. A single cavitation bubble is seeded with a pulsed laser in a free-falling and impacting water-filled test tube. After impact, a pressure wave containing compression and rarefaction phases is generated and interacts with ...

Shockwaves from air bubbles within pits induced by nearby cavitation bubbles
Ultrasonics SonochemistryThe cavitation intensity in near-boundary regions was significantly affected by the smoothness of boundaries. Micro pits on these boundaries may harbor smaller air bubbles or gas nuclei, and cavitation bubbles within cavitation clouds or cavitation ...

Rebounds of deformed cavitation bubbles
, 2018 Presented here are experiments clarifying how the deformation of cavitation bubbles affects their rebound. Rebound bubbles carry the remaining energy of a bubble following its initial collapse, which dissipates energy mainly through shock waves, jets ...

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.

Acta Physica Sinica, 2023 In this work, the interaction among multiple bubbles in a cavitation field is investigated by combining the experimental observation of small bubbles hovering around large bubbles. A model composed of three bubbles is developed, and the dynamic behavior of cavitation bubble is analyzed.

On the Collapsing Behavior of Cavitation Bubble Clusters [PDF]
The Proceedings of the Fluids engineering conference, 2000 The present paper reports observation results of collapsing cavity bubbles on a two-dimensional foil section by a high-speed video camera, together with impulsive force measurement. Results of numerical simulations of the behavior of bubble cluster corresponding to the above condition are also shown.
