acoustic cavitation的意思|示意

Acoustic cavitation（声波空化） is a type of cavitation that occurs when sound waves pass through a liquid. The pressure of the sound waves cause bubbles to form and collapse in the liquid, creating small pockets of gas that act as a propellant, pushing the liquid away from the source of the sound waves.

Acoustic cavitation has a variety of uses in industry, including cleaning and chemical processing. In cleaning applications, the bubbles created by the sound waves can dislodge particles from surfaces, making them easier to remove. In chemical processing, acoustic cavitation is used to mix or blend chemicals. The bubbles created by the sound waves assist in suspending and moving the chemicals around, improving reaction times and promoting uniformity in the process.

Acoustic cavitation can also be used in medical applications, such as breaking up kidney stones, destroying cancer cells, and removing plaque from arteries. The sound waves pass through the body and cause the formation of bubbles that vibrate at a high frequency. The resulting agitation of the bubbles’ walls can cause them to implode, releasing enough energy to break down kidney stones, cancer cells, and plaque.

Acoustic cavitation is also used for energy production, such as in the hydrogen fuel cell process. This process works by applying a high-frequency sound to a water-based solution, causing small bubbles to form. The bubbles then collapse, releasing energy in the form of hydrogen which can be used to power a fuel cell.

In conclusion, acoustic cavitation is a type of cavitation that occurs when sound waves pass through a liquid, causing bubbles to form and collapse. Acoustic cavitation is used in a variety of industries for cleaning, chemical processing, medical applications, and energy production.
