Spectral characteristics of acoustic cavitation

Ultrasonics, 1989
This paper reports on theoretical research into the dynamics, acoustic noise and noise spectrum of a single cavitation bubble affected by non-gradiental acoustic fields. It is shown that all the characteristic features of experimental acoustic cavitation spectra occur in the spectrum of a single bubble.

Energy Analysis in Acoustic Cavitation

Industrial & Engineering Chemistry Research, 2000
In sonochemical processes, the physical and chemical effects are attributed to the phenomenon of cavitation, which is the formation, growth, and collapse of the cavities termed as activity of cavities. Energy analysis of a single cavity has been considered in order to explain, qualitatively, the effects of acoustic parameters such as intensity and ...

Reactor with acoustic cavitation

The Journal of the Acoustical Society of America, 2002
The invention concerns a reactor with acoustic cavitation comprising a tube (10) made of flexible material, wherein the liquid to be treated circulates. Electro-acoustic transducers (1) are radially and uniformly distributed around the tube (10). Each electro-acoustic transducer (1) has a general prismatic shape with a base of specific width and a head

Acoustic cavitation and implosion acoustics

The Journal of the Acoustical Society of America, 1996
The ubiquitous cavitation bubble always seems to be around whenever one propagates an acoustic field of moderate amplitude through a liquid. The implosive collapse is a marvelously efficient concentrator of acoustic energy and can result in exotic mechanical and chemical effects. Examples of some of the many ways this acoustic energy can be utilized to

Acoustic detection of propeller cavitation

International Conference on Acoustics, Speech, and Signal Processing, 2002
Some of the acoustic correlations of cavitation noise caused by a propeller were analyzed. Digital signal processing techniques were used to quantify the dynamic structure of the cavitation produced by many ships. Consistent differences were observed between ships as to position, bandwidth, and rate of spectral transitions.

Biological Effects of Acoustic Cavitation

Ultrasound in Medicine & Biology, 1985
Although 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.
