Biological Effects of Acoustic Cavitation
Ultrasound in Medicine & Biology, 1985Although there is no basis in present knowledge to indicate that human subjects have been harmed in diagnostic applications of ultrasound, there is clear evidence of damage to lower organisms with temporal maximum intensities somewhat less than those available from certain diagnostic devices.

Cavitation enhanced acoustic hyperthermia
The Journal of the Acoustical Society of America, 2000The dominant mechanisms through which cavitation activity may lead to enhanced heating in tissue and tissue-like media with high-intensity focused ultrasound remain unclear. Previously, the authors have reported the results of experimental [J. Acoust. Soc. Am. 104 (A) (1998)] and numerical [ibid.

How acoustic cavitation can improve adhesion
Ultrasonics, 2012In general, ultrasound is commonly used at low power level for non-destructive testing (NDT) and detection of delaminations in adhesive bonded structures. The present paper instead presents an approach where power ultrasound is used to improve interface formation prior to the bonding process and to ensure the quality of adhesive bonds by using acoustic

Sonoluminescence and acoustic cavitation
Japanese Journal of Applied Physics, 2017Sonoluminescence (SL) is light emission under high-temperature and high-pressure conditions of a cavitating bubble under intense ultrasound in liquid. In this review, the fundamentals of the interactions between the sound field and the bubble, and between bubbles are explained.

Acoustic cavitation and sonoluminescence
The Journal of the Acoustical Society of America, 2000The violent collapse of a bubble in an acoustic field can lead to the emission of light, a phenomenon called sonoluminescence (SL). The study of sonoluminescence has led to refinements in understanding cavitation. This talk will focus on three areas of research in which the application of sonoluminescence is used to investigate cavitation: (1) In the ...

Acoustic cavitation: Sonic effervescence
The Journal of the Acoustical Society of America, 1994Bubbles intrigue and amuse young and old, scientist and nonscientist, alike. When acoustical waves either cause or enhance the activity of bubbles, a variety of phenomena can be observed, ranging from sonoluminescence to ultrasonic cleaning, and from acoustical attenuation in the ocean to microbubble formation in blood.

1981
Publisher Summary This chapter examines the types, stages, and effects of acoustic cavitation. Cavitation is defined as the formation of one or more pockets of gas in a liquid. The cavity's gas content refers to the liquid's vapor, some other gas, or combinations thereof. Cavitation tests are one way of characterizing the liquid medium.

Physics of Acoustic Cavitation
The Journal of the Acoustical Society of America, 1959A vocabulary useful in describing cavitation in an acoustic field will be defined, and concepts will be introduced to facilitate the interpretation of complex, many-bubble phenomena in terms of single-bubble dynamics. A distinction between stable cavities and transient cavities will be made and the roles of these two limiting types of bubbles in ...

Acoustically induced cavitation fusion
The Journal of the Acoustical Society of America, 1998In 1982, Hugh Flynn was issued a patent (No. 4,333,796) for a Method of Generating Energy by Acoustically Induced Cavitation Fusion and Reactor Therefor. Although it was largely ignored at the time, there have been several recent papers that treat the subject of acoustically induced fusion as quite plausible.
