Transient pulsations of cavitation bubbles [PDF]
The Journal of the Acoustical Society of America, 1986 Transient behavior of small gas bubbles in a liquid set into violent motion by ultrasonic pressure waves is of interest because of widespread use of microsecond pulses in diagnostic ultrasound. Such pulses contain only a few pressure cycles and the transient pulsations of bubbles set in motion by such pulses would determine the bubble-ultrasound ...

Ejecta‐Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion
Advanced Science, EarlyView.Stone motion during laser ablation is shown to result primarily from asymmetric cavitation bubble collapse, not from ejecta recoil. This challenges long‐standing assumptions and highlights the dominant role of bubble dynamics in laser–material interactions.

Cloud cavitation on an oscillating hydrofoil [PDF]
, 1994 Cloud cavitation, often formed by the breakdown of a sheet or vortex cavity, is believed to be responsible for much of the noise and erosion damage that occurs under cavitating conditions.

Introduction for amazing (cavitation) bubbles [PDF]
Interface Focus, 2015 Although the word ‘cavitation’ was originally coined by R. E. Froude and first cited by Barnaby and Thornycroft in 1895, the phenomenon was conjectured much earlier by L. Euler in his theory of water turbines in 1754. However, actual cavitation was first discovered and investigated by Barnaby and Parsons in 1893 when they found that the formation of ...

Covert cavitation: Spectral peak suppression in the acoustic emissions from spatially configured nucleations [PDF]
, 2017 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.

Advanced Science, EarlyView.Cell‐sized high‐frequency ultrasound using a lithium niobate transducer, previously ignored in reactive oxygen species (ROS) production, generated intracellular ROS at frequencies higher than conventionally used. The intracellular generation of ROS by cell‐sized high‐frequency ultrasound revealed in this study is expected to be applied to innovative ...

A Note on Partial Cavitation of Flat Plate Hydrofoils [PDF]
, 1955 Recently Tulin and Wu have treated the problem of fully developed cavitation on flat plate and cambered foils. In these treatments, the length of the cavity is always greater than the chord of the hydrofoil and the cavity is assumed to start at the ...

Observations of Cavitating Flow [PDF]
, 1994 This paper will present a review of some of the recent advances in our understanding of the dynamics and acoustics of cavitating flows. We focus first on the individual events which evolve from a single travelling nucleus and describe observations of the
