| 摘 要： | 用激光衍射技术测量了水平管内空气－水环状流携带液滴的粒径几何分布特性，得到了Ｓａｕｔｅｒ平均直径、体积平均直径、体积分数、折算表面积等描述粒径几何特性的参数；用双参数模型描述了液滴粒径的分布，研究了折算气速、液相折算雷诺数对液滴粒径分布的影响；并利用双平行电导探针测量了气液界面波，根据界面结构分析了环状流中液滴携带的方式．

| Abstract: | Laser diffraction technology is used to measure the distribution of liquid drop size of air water in horizontal pipe. Sauter mean diameter, volume concentration and mean diameter to volume ratio are obtained. The air water interface waves were monitored by two parallel conductance probes. The effect of surperfical air velocity, surperfical liquid velocity, liquid film velocity on distribution of liquid drop size was examined. The mechanism of liquid drop entrainment was studied and analyzed. |
