WebUltrasonic Cavitation in Liquids Ultrasonic waves of high intensity ultrasound generate cavitation in liquids. Cavitation causes extreme effects locally, such as liquid jets of up to 1000km/hr, pressures of up to 2000atm and temperatures of up to 5000 Kelvin. About ultrasonic cavitation WebThe evaluation of the acquired data shows that a frequency component which is 3/2 times the driving frequency (∼30 kHz) can be used to determine the onset of transient cavitation. Once the transient cavitation threshold has been exceeded, broad band noise levels show a good correlation with cavitation intensity. Keywords:
