ABSTRACT
In an acoustic wave, which creates periodic rarefaction, cavitation is observed at very high wave intensities, which are realized at ultrasonic frequencies. Cavitation processes play an important role in practical applications of ultrasound; for this reason, a great deal of attention is devoted to the study of ultrasonic cavitation. One of the basic questions arising in the study of ultrasonic cavitation is the question of how the liquid ruptures in an ultrasonic wave at acoustic pressures far below the theoretical rupture strength of the liquid. In reality, a cavitation bubble contains some gas, whose mass remains practically constant with a rapid collapse. It is also necessary to take into account the fact that for rapid collapse there is not enough time for the saturated vapor filling the cavitation cavity to condense on the surface of the cavity.
