We investigated the relation between the sonochemical efficiency and the ultrasound field under sonication in a rectangular sonochemical reactor equipped with five asymmetric transducers. We observed ultrasound field in the rectangular sonochemical reactor with the sheeted laser and luminol solution. The reactor consisted of the 485kHz five asymmetric transducers and the rectangular glass cell of 20cm×20cm×65cm. The experimental setup was shown in Fig.1. All measurements were carried out at room temperature. Mechanical stirring leads to complex asymmetric cavitation behavior and fluid convection in the reactor. With a mechanical stir, the region showing the sonochemical luminescence expanded and sonochemical efficiency increased up to about 1.9 times than the value obtained with five symmetric transducers. From these results, the configuration of the transducers orienting the four corners and stirring leads to enhance the sonochemical efficiency.
