| 摘 要： | 研究了重力跳动对液桥表面及内部流体流动的影响, 以期明确重力跳动对多相流体系统的作用效果. 理论研究表明, 当重力跳动作用于液桥时, 液桥反响频率的大小取决于液桥尺寸和物性参数; 实验研究显示重力跳动引入的液桥表面振动、液桥内部流动与温度振动之间存在着三角耦合关系; 数值模拟结果揭示了重力跳动作用于液桥时液桥内部流体的流动结构. 另外, 对理论、实验与数值模拟结果进行了对比验证, 得到了吻合一致的结果.

| Abstract: | The effects of G-Jitter on the surface oscillation and internal flow structure of a liquid bridge have been investigated in order to understand the effect of G-Jitter on the multiphase fluid systems.The theoretical analysis shows that the resonance frequency of the liquid bridge changes depending on the size and physical property of the liquid bridge.The experimental study indicates that there may be a triple coupling link between the vibration-induced surface oscillations and flow/temperature oscillations ... |
