Abstract:
It is known that sonochemical reactions are enhanced by pulsing ultrasound. A method to optimize a sonochemical reactor using a pulsing operation was studied through the measurement of changes in sonoluminescence (SL) intensity from distilled water under various experimental conditions. It was confirmed that pulsing with a constant input power level enhanced SL intensity at lower power levels because of the higher amplitude of ultrasound. In contrast to this, a quenching effect due to excessive sound pressure appeared at higher power levels, and the pulsing operation was not effective under these conditions. Pulsing is more effective at higher frequency than at lower frequency.
