• Cavitation-induced nucleation

An effective and reliable method to generate ice slurry is necessary for cold-energy storage and transport systems. First we found that ice slurries were generated in supercooled water by ultrasonic vibration. Then we experimentally studied the effect of bubble nuclei on the phase change from supercooled water to ice induced by ultrasonic vibration. Our results show that the phase change is closely related to acoustic cavitation, and the probability of the phase change increases as the total number of bubble nuclei increases. Finally, simulation results based on the cavitation-induced nucleation of solid qualitatively agree with the experimental results.
