Active control of phase change from supercooled water to ice by ultrasonic vibration 1. Control of freezing temperature

摘要

A method to actively control the supercooling of water is a critical issue in cold-energy storage and transport systems that use ice slurries. We experimentally studied the use of ultrasonic vibration to control the phase change from su- percooled water to ice, and simulated the phase assuming that ultrasonic-induced cavitation influences ice nucleation. The experimental results indicated that ultrasonic vibration strongly promotes the phase change from su- prcooled water to ice and that a reliable method to actively control the phase change by ultrasonic vibration can be realized. The results of the simulation agreed well with the experimental results.
