重力跳动对多相流体系统的影响

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.

Study on Detection of Negative Corona Discharge Generated in Rod-Plane Air Gap by Using External Electrode Method

A detective method of a negative corona discharge by means of an external electrode is presented. The relationship between an area of the external electrode and a detected voltage waveform is examined experimentally. This experimental study is carried out with the use of a rod-plane air gap. The results obtained will be applicable to problems associated with silos, ducts, and high-voltage equipment.
