中文摘要	对垂直环形管内上升气液两相泡状流存在条件进行了研究 .根据Taitel的气泡结合及积聚理论及小气泡群的实际上升速度 ,将小气泡和Taylor气泡上升速度与截面含气率进行关联 ,并采用Das的预测垂直环形管内Taylor气泡上升速度的关系式 ,获得了一种改进的泡状流区存在模型 .通过该实验数据及其他研究者实验数据的比较 ,表明该改进模型比Caetano模型更加符合实际 .通过上述类似方法 ,笔者还给出了倾斜环形管内泡状流的存在模型 .; In this paper, the condition of bubble flow region existence is studied for upward gas liquid flow in a vertical annulus. According to Taitel’s bubble coalescence theory and the actual rise velocity of a swarm of small bubbles in vertical tubes, the void fraction is correlated with the rise velocities of small bubbles and Taylor bubble in vertical tubes using Gas correlation predicting Taylor bubble rise velocity, and a modified model on bubble flow region existence is obtained. Experimental data from present work and other researchers show that present model is better than Caetano model. Finally, the model on bubble flow region existence for two phase flow in inclined annulus is given.; 【作者单位】集美大学机械工程学院；西安交通大学动力工程多相流国家重点实验室福建厦门361021；陕西西安710049；【作者英文名】ZHANG Jun 1,CHEN Ting-kuan 2 (1.
