ultrasonic vibration

Ultrasonic Power Transducers | International

Cavitation occurs when the vibration of a transducer surface interfacing with a liquid (usually water, but possibly a water / organic solvent mixture in an ultrasonic cleaning application) is sufficient to create a partial vacuum that exceeds the vapor pressure of the liquid, and bubbles form at the vibrating surface.
