Abstract Ultrasonic cavitation is shown to hamper the supercooling required for the nucleation of water. To elucidate the mechanism of nucleation of ice under ultrasonic cavitation, ultrasound waves were applied to supercooled water with oxygen contents of 4.06, 4.48, 4.95, 5.62, and 6.34 mg L−1. Ultrasonic waves were intermittently applied at temperatures below 0 °C. Nucleation temperatures were measured under different experimental conditions. The maximum nucleation temperature (−3.66 ± 0.39 °C) was observed for a water sample containing 4.95 mg L−1 oxygen, at 319 W power (electric power of ultrasound). At 319 W, the intensity of cavitation in this water sample was less than that at higher power. It is concluded that compared with the effect of pressure produced by cavitation, the effect of heat produced by cavitation is significant during the nucleation of water with high-intensity ultrasonic cavitation.

超声对不同含气量水成核温度的影响

摘要 超声空化会阻碍水成核所需的过冷。为了阐明超声空化作用下冰的成核机制，将超声波应用于含氧量为 4.06、4.48、4.95、5.62 和 6.34 mg L-1 的过冷水。在低于 0 °C 的温度下间歇性地施加超声波。在不同的实验条件下测量成核温度。对于含有 4.95 mg L-1 氧的水样，在 319 W 功率（超声波功率）下观察到最大成核温度 (-3.66 ± 0.39 °C)。在 319 W 时，该水样中的空化强度低于更高功率时的强度。得出的结论是，与空化产生的压力影响相比，
