Abstract
Acoustically induced cavitation at 20 kHz is observed by means of high speed CCD recording at a framerate of 2250 per second. Using digital image processing the bubblesʹ trajectories are reconstructed. The experimental data reveal that collision and coalescence of bubbles is a predominant phenomenon that limits their individual lifetime. Measurements of bubble sizes and velocities are in agreement with previous results.
