Sonoluminescence, sonochemistry (H2O2 yield) and bubble dynamics: frequency and power effects.

In the present work, comprehensive experimental and numerical investigations on the effects of ultrasound frequency and acoustic power on sonoluminescence (SL) and H(2)O(2) yields have been carried out. The multibubble SL and H(2)O(2) yields have been examined for four frequencies (213, 355, 647 and 1056 kHz) and over a wide range of acoustic powers. The observed experimental results have been discussed with respect to single bubble dynamics and the number of active cavitation bubbles.
