Bubbly ultrasound
WebMar 1, 2011 · The study of ultrasonic waves in sonoreactors in which bubbles are present in the liquid is a challenge, as it has not been exhaustively studied. The useful effects in sonochemistry appear above an intensity threshold for which the required amplitudes generate nonlinearity.
