Technical documentation on the use of fine bubbles (microbubbles) in ultrasonic applications - Deaeration fine bubble generation liquid circulation device.

Acoustic flow control technology using ultra-fine bubbles and megahertz ultrasound.

<<Deaeration Fine Bubble Generation Liquid Circulation Device>> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gas to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gas decreases, the bubble size of the dissolved gas due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles of less than 20μ are generated. The above describes the state of the deaeration microbubble generation liquid circulation device. 5) When ultrasonic waves are applied to the above-mentioned deaeration fine bubble generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles, and when measuring the fine bubbles, the distribution of ultrafine bubbles becomes greater than that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled. 6) In the state where ultrasonic waves can be stably controlled, the original product: a megahertz ultrasonic oscillation control probe is used to control the oscillation of megahertz (1-20 MHz) ultrasonic waves. The method of controlling the sound pressure level is achieved by controlling the original nonlinear resonance phenomenon of liquid circulation and megahertz ultrasonic waves, setting and controlling it to an effective dynamic state.

Development of "Control Technology for Nonlinear Phenomena" Using a Small Pump

The Ultrasonic System Research Institute has developed "ultrasonic control technology" that dynamically controls nonlinear phenomena related to ultrasonic propagation by utilizing a small pump for liquid circulation. Nonlinear phenomena are evaluated through analysis using an ultrasonic tester. The complex changes in ultrasound (such as ultrasonic cleaners, ultrasonic probes, etc.) are confirmed through time-series data analysis of sound pressure from ultrasonic oscillation and reception, identifying various interactions. Based on the confirmation of these interactions, the oscillation control conditions using ultrasonic probes are optimized, achieving a dynamic ultrasonic control system tailored to specific objectives. In practical applications, such as ultrasonic cleaning, the ON/OFF control (or control of flow rate and velocity, etc.) of the current liquid circulation device is optimized by considering the ultrasonic propagation characteristics related to the installation state of the device and the surface elastic waves of the target object, including the output, oscillation frequency, and control conditions of the ultrasound. In particular, by utilizing the vibration characteristics of the pump to alternately circulate liquid and gas, new nonlinear effects of ultrasound and microbubbles are realized.
