Acoustic cavitation prediction
The Journal of the Acoustical Society of America, 1978We have derived an approximate expression for the threshold pressure for transient acoustic cavitation and have used this result with published expressions for the thresholds for gas bubble nucleation and for rectified diffusion in synthesizing cavitation prediction charts for water covering a frequency range from 10 kHz to 2.5 MHz, and for gas ...

The Journal of the Acoustical Society of America, 1983
Abstract : The primary thrust of this study was toward a more complete understanding of general aspects of acoustic cavitation. The effect of long- chain polymer additives on the cavitation threshold was investigated to determine if they reduced the acoustic cavitation threshold in a similar manner to the observed reduction in the cavitation index in ...

Ultrasonics, 1984
Abstract This article presents a selective review of the subject of acoustic cavitation inception. Topics covered include cavitation threshold measurements, the role of dirt or pre-existing bubble nuclei in cavitation inception, radiation-induced acoustic cavitation, and a discussion of some unsolved problems such as cavitation thresholds in liquid ...

The Journal of the Acoustical Society of America, 2003
Acoustic cavitation is a phenomenon that occurs on microsecond time scales and micron length scales, yet, it has many macroscopic manifestations. Accordingly, it is often difficult, at least for the author, to form realistic physical descriptions of the specific mechanisms through which it expresses itself in our macroscopic world.

06THRESHOLDS OF ACOUSTIC CAVITATION.
1964Abstract : 27Cavitation thresholds in water were measured as a function of frequency, dissolved gas, ambient pressure, and suspended particle size. The apparatus used comprises a two-liter volume of water enclosed by a spherical glass shell driven at its radially symmetric resonance frequencies by eight multiresonant piezoelectric transducers.

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 ...

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.

Sonic Effervescence: A Tutorial on Acoustic Cavitation
The Journal of the Acoustical Society of America, 1997This article on acoustic cavitation is a revision of a tutorial lecture presented at the Acoustical Society of America meeting in Austin, Texas, on 28 November 1994. The general approach adopted here differs from a review article in stressing the overarching themes that come under the category of acoustic cavitation, rather than being an encyclopedic ...
