On acoustic cavitation of slightly subcritical bubbles [PDF]
The classical Blake threshold indicates the onset of quasistatic evolution leading to cavitation for gas bubbles in liquids. When the mean pressure in the liquid is reduced to a value below the vapor pressure, the Blake analysis identifies a critical ...

Taming Acoustic Cavitation [PDF]
In this fluid dynamics video we show acoustic cavitation occurring from pits etched on a silicon surface. By immersing the surface in a liquid, gas pockets are entrapped in the pits which upon ultrasonic insonation, are observed to shed cavitation bubbles.

Identification of Cavitation by Noise [PDF]
The identification of cavitation is very important in technical practice for operational and especially economic reasons. The article deals with the use of another way to measure noise during cavitation.

Covert cavitation: Spectral peak suppression in the acoustic emissions from spatially configured nucleations [PDF]
Dual laser-nucleation is used to precisely configure two cavitation bubbles within a focused ultrasound field of f0 = 692 kHz, in proximity to the tip of a needle hydrophone.

Inner surface peening for long and narrow helical pipe using acoustic cavitation
The inner surface peening of helical pipes is highly challenging due to the inaccessibility of the inner surface. To the end, we propose to peen the inner surface by introducing acoustic cavitation inside the pipe. We also provide a theory to account for

The role of ultrasound-driven microbubble dynamics in drug delivery : from microbubble fundamentals to clinical translation [PDF]
In the last couple of decades, ultrasound-driven microbubbles have proven excellent candidates for local drug delivery applications. Besides being useful drug carriers, microbubbles have demonstrated the ability to enhance cell and tissue permeability ...

Observations and scaling of travelling bubble cavitation [PDF]
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.
