Abstract:
According to the principle of Luminol increasing sonoluminescence (SL), the ultrasonic field in cleaning tank is measured with the glimmer measurement system and the relationship between SL intensity and both the power density and acoustic frequency is analyzed. The results show that only when the input power density exceeds the threshold value of SL intensity, SL will happen. Moreover, in the same power density, different frequency correspond to different luminous intensity.
