Abstract

Bubble cloud dynamics and acoustic waves at cavitation after a focused shock wave are investigated experimentally by high-speed photo-recording and fiber-optic hydrophone measurements. Secondary acoustic waves from finite cavitational clouds far from boundaries and near to the free surface are observed. The correlation between secondary acoustic cavitation waves and luminescence at an early stage of cavitation is discussed.
