| Abstract: | A circuit for producing micro-bubbles based on ultrasonic cavitation was investigated and designed.Certain sinusoidal signal,which was produced by using the AD9850 and power amplified,drove the transducer to be cavitating and then to produce micro-bubbles.The resistant moment of turning plate was analyzed.An experimental procedure matched this method was brought forward.The results indicate that the micro-bubbles produced by this method have an efficient drag reduction and the method can be realized easily ... |
