摘要:
Evidence is presented of the dynamic nucleation of ice induced by an isolated stable cavitation bubble in undercooled water. The evidence supports the notion of dynamic nucleation as a result of the freezing point shift due to high pressure pulses associated with a collapsing bubble. It is found that the cavitation bubble requires minimum undercooling, 5 K, to initiate nucleation on ice. This undercooling may be attributed to the temperature rise of the water due to the heat generated by compression of the bubble or the undercooling required for normal ice to nucleate on a high pressure phase. ©1998 American Institute of Physics.
