In order to develop the ultrasonic reactor, the effects of the arrangement of ultrasonic transducers and the superposition of ultrasonic fields on the sonochemical reaction performance were experimentally investigated. Two PZT transducers at 176 kHz were used. The effects of installation position (bottom or side) of transducer and the distance between two transducers on the sonochemical reaction rate were small. By using the orthogonal superposition of ultrasonic fields, the synergy effect of sonochemical reaction rate was observed. At the part of orthogonal superposition of ultrasonic fields, the intensity of sonochemical luminescence becomes stronger. From these results, it is considered that the area where acoustic pressure is higher than cavitation threshold becomes larger by using the orthogonal superposition of ultrasonic fields.
