Метод идентификации стадий развития кавитации в жидкостях и гелевых имитатах биологических структур

Abstract

The development of cavitation zone has been studied in liquids as well in gel imitators of biological structures. Experiments have been done for two different conditions: constant voltage applied to the transducer and linearly increasing voltage. Cavitation activity was estimated by the sonoluminescence (SL) intensity. Hydrophone output was registered simultaneously with the SL intensity. Four stages of cavitation zone development have been separated. It has been shown that spectra of cavitation noise are different at different stages. A method for the identification of the above stages has been proposed.
