窄脉冲声场中空化峰对声化学反应器设计的作用

The Effect of Cavitation Peak to Sonochemical Reactor Designing

用声致发光在声强<0.5W/cm2时记录到脉冲声场中脉冲占空比为1∶1,脉冲宽度为300～400μs时空化效应出现峰值,即出现空化峰。这一效应对于在低声强(<0.7W/cm2)

Ultrasound of frequency 1.1 MHz was used to record cavitation peak in pulsed ultrasonic field. It is found that cavitation peak appears in μs pulse length. This effect is useful to sonochemical reactor designing.
