Abstract:
A method for freezing supercooled water, comprising:filling said supercooled water in a sealed container, mixing bubbles into the supercooled water comprising one of (i) reducing pressure of said supercooled water to generate bubbles from the supercooled water and mixing said generated bubbles in the supercooled water, (ii) providing a bubble-mixing inlet and reducing pressure of the supercooled water to mix bubbles into the supercooled water from outside of the container through the bubble mixing inlet, or (iii) providing a bubble-mixing inlet, introducing bubbles into the supercooled water from outside the container through the bubble-mixing inlet under pressure, and mixing the bubbles into the supercooled water; simultaneously repeating expansion, compression, disruption, clustering and disappearance of the bubbles mixed into the supercooled water; and freezing the supercooled water by vigorously oscillating gas-liquid boundaries between the bubbles and the supercooled water.
