This article reviews the role of cavitation in the therapeutic applications of ultrasound and laser surgery, and the cavitation effects in mechanical heart valves. Whenever laser pulses are used to ablate or disrupt tissue in a liquid environment, cavitation bubbles are produced which interact with the tissue. The interaction between cavitation bubbles

The Dynamics of a Cavitation Pocket and Cavitation Damage
Journal of Machinery Manufacture and Reliability, 2019The motion of a liquid column in a vertical tube caused by a moving piston that contacts its lower boundary is considered. The law of the piston’s motion is defined based on experimental data. The acceleration of the piston exceeds the acceleration due to gravity.

Critical Reviews™ in Biomedical Engineering, 2006
Acoustic cavitation takes place when tiny gas bubbles oscillate, grow, and collapse in liquid under the influence of ultrasonic field. This study reviews cavitation bioeffects that are found both in vivo and in vitro when exposed to either low- or high-power acoustics.

Laser-Induced Cavitation and Photoacoustic Cavitation
2015As a physical phenomenon, cavitation can be induced by several factors, including heating, acoustic pressure, and high-energy light, for which a focused laser has been widely used.

Science
Cavitation, characterized by formation of vapor bubbles in a low-pressure or high-temperature region of a liquid, is often destructive, but it can be harnessed for actuators and robots. We exploit cavitation to accumulate substantial energy in superheated liquids by suppressing its immediate release until reaching a stability limit.

Cavitation nuclei and cavitation noise
The Journal of the Acoustical Society of America, 1988Present understanding of the influence of nuclei on the onset of cavitation and the generation of radiated cavitation noise is reviewed. It is now generally accepted that the formation of cavities in a liquid at only moderate negative pressures requires the presence of nuclei in the liquid; the experiments of Greenspan and Tschiegg, among others, leave

This article describes the fundamental phenomena of cavitation. The distinctive characteristics of cavitation in the marine applications, especially in the propellers, are introduced. This article explains first the quasi-steady processes in phase transitions of pure substances.

Abstract ‘Cavitation is a most unpleasant hydrodynamic phenomenon, whose harmful effects are both widespread and obvious, and seriously handicap many areas of science and engineering. Conversely, its basic nature has long been veiled in mystery and only recently is it beginning to be understood’ wrote Knapp et al. (197GB).

Coccidioidal pulmonary cavitation
The American Journal of Medicine, 1958Abstract 1.1. Seventy-seven cases of coccidioidal pulmonary cavitation have been summarized. 2.2. Cavitation is found in about 1 to 3 per cent of hospitalized patients with coccidioidomycosis, or about 0.1 per cent of all patients with this disease. 3.3.
