本研究的主要目的是探索在减重力环境中利用液-气相变现象强化传热机制的可能性。为了保护沸腾表面，应避免由于形成蒸汽层而引起的温度突变，并研究了低频振动作为一种预防技术。利用流体体积法在二维数值域中对单气泡动力学进行了数值模拟，以了解在低频振动和重力影响下液-气相变的基本行为。所有模拟均针对具有固定壁面过热的饱和水进行。 通过改变重力、振动位移和振动频率来监测气泡生长、气泡离开时间和传热系数。月球重力条件下的气泡脱离时间与地球重力条件下的气泡脱离时间相匹配，至少需要1g的加速度振幅。研究发现，在某些振动条件下，气泡分离可能会延迟，这表明加速度振幅可以作为气泡分离的直观指标，而不是单个频率和振幅。引用:佛罗里达州奥兰多2020年冬季会议论文

The main objective of this study is exploring the possibility of using liquid to vapor phase change phenomenon to enhance the heat transfer mechanism in a reduced gravity environment. An abrupt temperature jump by forming a vapor layer should be avoided to protect the boiling surface and low frequency vibration is studied as a prevention technique. Numerical simulation of single bubble dynamics is performed in a two-dimensional numerical domain using the volume of fluid method to understand the fundamental behavior of liquid to vapor phase change under the influence of low frequency vibration and gravity. All simulations are carried out for saturated water with a fixed wall superheat. The bubble growth, the bubble departure time, and the heat transfer coefficients are monitored by varying gravity, the vibration displacement, and the vibration frequency. At least 1g acceleration amplitude is required to match the bubble detachment time at the Moon’s gravity condition to that of the Earth. It was found that bubble detachment could be delayed in some vibrating conditions, suggesting that the acceleration amplitude may be utilized as an intuitive indicator for bubble detachment rather than individual frequency and amplitude.
