Cavitation effect of ultrasonic vibrating rod:

In some cases, the generation of ultrasonic effect is related to the cavitation mechanism. Acoustic cavitation refers to a series of dynamic processes that occur in tiny bubbles (holes) in the liquid under the action of sound waves: oscillation, expansion, contraction and even collapse. At the place where cavitation occurs, the local state of the liquid changes greatly, resulting in extreme high temperature and high pressure.

component:

① Ultrasonic transducer ② ultrasonic horn ③ ultrasonic tool head ④ ultrasonic drive power supply. Its manifestation is that the transducer moves back and forth in the longitudinal direction, and the amplitude is generally several microns. Such amplitude power density is not enough and cannot be used directly. The horn amplifies the amplitude according to the design requirements, isolates the reaction solution and the transducer, and also plays the role of fixing the entire ultrasonic vibration system. The tool head is connected with the horn, which transmits the ultrasonic energy vibration to the tool head, and then the tool head transmits the ultrasonic energy into the chemical reaction liquid.
