Periodic shock-emission from acoustically driven cavitation clouds: a source of the subharmonic signal
(Peer reviewed; Journal article, 2014-12)Single clouds of cavitation bubbles, driven by 254 kHz focused ultrasound at pressure amplitudes in the range of 0.48–1.22 MPa, have been observed via high-speed shadowgraphic imaging at 1 × 10⁶ frames per second. Clouds ...
