Анотация: Abstract.The ultrasoniccavitationactivity in aqueous solution of carbon dioxide was studied. The ICA-3M cavitometer which principle is based on recording the intensity of the high-frequency part of the cavitation noise(CN) spectrum was used for cavitation activity estimation. Erosion rate was also estimated in a number of regimes. The spectra of cavitation noise were recorded as well. It is shown that in a supersaturated solution of carbon dioxide the cavitation activity is about zero. During the degassing process cavitation activity grows and tends to the limit of the activity level in distilled water. Based on the cavitation noise spectra analysis it was concluded that at the first stage of degassing, intense shock waves are not generated by bubbles and cavitation in this mode cannot have an intensive destructive effect on solid surfaces and biological tissues and cells. At the second stage the situation changes and the concentration of rapidly collapsing bubbles increases significantly.
Ключевые слова: Keywords: acousticcavitation, carbon dioxide solution, cavitation activity, bubble collapse.
