摘要
用ＥＫＴＰＲＯ１０００高速动态分析仪对弹状流中长气泡的运动进行了研究．获得了无干扰流场的测量数据，给出了气泡形状及其上升速度的实验结果．根据长气泡的流动条件，对它们进行了分类．实验数据与已有的研究结果进行了比较，两者符合良好．
A long bubble rising in flowing liquid in a vertical tube is one of the most fundamentalphenomena of gas-liquid two-phase flow. An experimental study on this phenomenon is carried out. The non-invasive measurements of the gas-liquid flow field are obtained by usingthe EKTAPRO 1000 high speed motion analyzer. The rising velocity and the shape of longbubbles are investigated. The experimental data are compared with the existing practical ortheoretical correlations and a good agreement is obtained.
