Acoustic cavitation in cryogenic and boiling liquids

Abstract

Vapour bubble dynamics in cryogenic and boiling liquids affected by an acoustic field is considered. Linear pulsations and nonstationary growth of vapour bubbles in time due to linear effects of rectified heat and mass transfer are studied. The growth thresholds of vapour bubbles depending on thermodynamic parameters of liquid, static overcompression, and acoustic field frequency are presented. Essential influence of resonance properties of bubbles on the values of growth thresholds is shown. The results for different cryogenic liquids and boiling water are given.
