| 摘 要： | 应用分流层的平衡液膜理论和有限振幅界面波的势流理论，以不稳定界面波生长至波幅可跨接水平管上管壁为液弹形成的充分条件，导出了水平管弹状流液弹频率的计算模型．应用电导探针在内径２４ｍｍ、长度与内径之比大于６００的水平管中测量了水－空气弹状流的液弹频率．模型计算结果与试验结果相吻合．

| Abstract: | A model for predicting slug frequency of horizontal slug flow was derived based on the concept of equilibrium liquid film and the potential analysis for finite amplitude interfacial wave in stratified flow. Slug formation due to bridging the up wall of horizontal pipe by growing interfacial wave was assumed. Slug frequencies of air water flow were measured by electrical probe in a horizontal pipe with a diameter of 24 mm, and the ratio of length to diameter over six hundreds. The predicted results agree well with the test data. |
