MS ソノリアクター設計 : 超音波振動子の駆動について
詳細
The drive method of ultrasonic transducers is explained in order to design sonochemical reactors. The impedance of piezo electric ceramics changes with resonance frequency. Moreover, since ultrasonic wave is reflected with the water surface or a vessel wall, water resonates on some conditions and the impedance of a transducer also changes. The optimal drive frequency is obtained by monitoring the imrjedance of a transducer.
