| 摘 要： | 对垂直同心环形管内上升气液弹状流向团状流的转换进行了一定的研究。根据弹状流及团状流的流动特性 ,并考虑同心环形管的结构特征 ,建立了垂直同心环形管上升气液团状流向环状流转换的新的理论模型。通过文中的实验数据及其他研究者的实验数据对该模型的预测性能进行了检验 ,并与其他研究者的模型进行了比较 ,最后还对环形管结构参数对转换的影响进行了一定的分析。

| Abstract: | The transition from slug flow to churn flow for upward gas liquid in vertical concentric annulus is studied and a transition model is developed considering the structural feature of the concentric annulus and the flow characteristics for slug and churn flow in the concentric annulus. Compared with other existing models and the experimental data, the present model is in better agreement with experimental data than existing models. Finally, the effect of the structural parameters of the annulus on transition boundary is analyzed. |
