A method of measuring the spectral distribution of cavitation nuclei in liquid in the form of gas bubbles is described and the results of tests for determining the number of nuclei in the water supply line are given. The property of gas bubbles to cause absorption of ultrasonic energy propagating in the medium water gas bubbles was established as a means for measuring the spectral distribution of cavitation nuclei. It was also shown that the basic causes of ultrasonic energy absorption were: (1) the transfer of heat from the bubbles to the liquid during periodic changes in volume under the effect of a sound wave, (2) dissipation of a part of the energy, since a bubble of resonance dimensions becomes itself a spherical emitter of sound.

Mechanics Of Underwater Noise written by Donald Ross and has been published by Elsevier this book supported file pdf, txt, epub, kindle and other format this book has been release on 2013-10-22 with Science categories.
Mechanics of Underwater Noise elucidates the basic mechanisms by which noise is generated, transmitted by structures and radiated into the sea. Organized into 10 chapters, this book begins with a description of noise, decibels and levels, significance of spectra, and passive sonar equation. Subsequent chapters discuss sound waves in liquids; acoustic radiation fundamentals; wind-generated ocean ambient noise; vibration isolation and structural damping; and radiation by plate flexural vibrations. Other chapters address cavitation, propeller cavitation noise, radiation by fluctuating-force (dipole) sources, and mechanical noise sources. This book will be helpful as a self-education text and as a reference for workers in the field.

The report describes an experiment performed to verify the neutralization of the bubble buoyancy in cavitation nuclei. Distilled and tap water which stood for several days was subjected to normal air saturation and a given atmospheric pressure and temperature. Additional nuclei were created by means of an impeller placed on the shaft of a small electric motor with the pump rpm and time element remaining constant. Results of the experiment indicate that with identical mixing of fluids with varying concentrations of solid impurities, the quantity of gas bubbles formed in tap water greatly exceeds the bubble content of distilled water. It is concluded that the experimental investigations agree with the proposed hypothesis of the mechanism of the prolonged existence of microscopic cavitation nuclei in a fluid. (Author).
