説明
In order to confirm the effect of ultrasonic wave on the freezing of supercooled water, various level of ultrasonic waves were applied to the supercooled water. The frequencies of the waves applied were 28kHz, 40kHz, 45kHz, 50kHz, and 1MHz. In order to clarify the mechanism of the effect of the ultrasonic wave, several factors were examined changing the experimental conditions and the results were compared each other; the factors were the existence of a free surface or oil -water interface, the volume of water, the purity of water and the existence of metal bar inserted. Each test section was cooled at a constant cooling rate and the ultrasonic waves were applied to each test section continuously, varying the frequency and the intensity. The experiments were carried out until the water in the test section solidified. The degree of supercooling at the freezing is determined by measuring the temperature just before a rapid increment of temperature due to freezing. It was found that the existence of a free surface and insertion of a metal bar with an addition to the ultrasonic wave have effects on the freezing of supercooled water. On the other hand, if oil-water interface or no metal bar insertion was selected as the experimental condition, there was no influence of the ultrasonic wave on the freezing of the supercooled water even the frequency and the intensity were varied.
