Abstract(in English) | Effect of second-harmonic superimposition on sonochemical reaction was investigated.The minimum acoustic power for iodide oxidation induced by focused ultrasound at 750 kHz with a superimposed wave at 1.5 MHz using a confocal transducer was 3 times lower than that induced by ultrasound at 750 kHz or 1.5 MHz. The rate of iodide oxidation induced by plain wave ultrasound at 1 MHz with a superimposed wave at 2 MHz showed significant dependence on the phase relation between the two waves.The.largest rate was obtained at the relative phase which maximizes the magnitude of negative peak pressure.The dependence of sub-harmonic emission on the ultrasound power was studied with the same plain wave ultrasound transducer.The results also showed the synergistic effects of the fundamental and second harmonic waves. |
