Ultrasonic Vibration 1

Active control of phase change from supercooled water to

Dec 01, 2001Then, the phase change from supercooled water to ice induced by ultrasonic vibration was simulated based on the cavitation phenomena. Our findings are summarized as follows: 1. Ultrasonic vibration strongly promotes the phase change from supercooled water to ice, for both pure water and tap water.
