Condensing Behavior of a Freon Bubble with MPS-MAFL

In the study,MPS-MAFL is used to simulate the phenomenia of a Freon bubble condensing in a subcooled pool.The sensitivity on pool subcooling is also studied to understand the condensation behavior.The simulating shows that the bubble pressure decreases as the condensation begins with the shrinking of the interface.At the later phase of the condensation,the bubble pressure becomes larger than that of the circum-stance.A peak pressure will emerge at the moment that the bubble collapses and there will be a maximum pressure value at a certain subcooling.As the subcooling increases or decreases,the peak pressure will drop and may fade away.The maximum pressure is 3.12MPa at a subcooling about 20℃.
