We use focused ultrasound bursts to submit a liquid to mechanical tension. When the pressure in the sound wave reaches a sufficiently low value, vapor bubbles are nucleated in the bulk liquid. According to nucleation theory, increasing the ultrasound frequency increases the cavitation threshold by a calculable amount. To check this, we have built a fiber optic probe hydrophone based on one originally proposed by Staudenraus and Eisenmenger [Ultrasonics 31, 267 (1993)]. We have adapted the…

Negative Pressures and Spallation in Water Drops Subjected to Nanosecond Shock Waves.

TLDR
This work generates tension pulses with nanosecond rise times in water by reflecting cylindrical shock waves, produced by X-ray laser pulses, at the internal surface of drops of water, using a nucleation-and-growth model that explains how rapid decompression could outrun heterogeneous cavitation in water, and enable the study of stretched water close to homogeneous Cavitation pressures.

Cavitation in heavy water and other liquids.

TLDR
The results indicate that the cavitation threshold approaches the prediction of CNT as the surface tension gets smaller, which raises the question of the validity of a simple theory such as CNT to account for high surface tension liquids and suggests that an appropriate microscopic model of such liquids may be necessary to correctly predict the Cavitation threshold.

Pressure Sensitivity of a Fiber-Optic Microprobe for High-Frequency Ultrasonic Field

An acoustic microprobe is required to measure high-frequency ultrasonic fields with good spatial resolution. An optical fiber microprobe was proposed in our previous study, which consists of a small

Cavitation pressure in water.

TLDR
This work investigates the limiting mechanical tension (negative pressure) that liquid water can sustain before cavitation occurs, and describes the method which consists in focusing a high amplitude sound wave in the bulk liquid, away from any walls, to obtain highly reproducible results.

Water at the cavitation limit: Density of the metastable liquid and size of the critical bubble

The ability of a liquid to sustain mechanical tension is a spectacular manifestation of the cohesion of matter. Water is a paradigmatic example, because of its high cohesion due to hydrogen bonds.

TLDR
Theoretical and experimental aspects of an extrinsic optical-fiber ultrasound sensor based on a thin transparent polymer film acting as a low-finesse Fabry-Perot cavity that is mounted at the end of a multimode optical fiber suggest that it may find application as an alternative to piezoelectric devices for the detection and measurement of ultrasound.
