摘要对垂直同心环形管内上升气液团状流向环状流的转换进行了研究。
In this paper , the transition from churn flow to annular flow for upward gas - liquid in vertical concentric annulus is studied and a transition model is developed by considering the structural feature of the concentric annulus and the flow characteristics for churn and annular flows in the concentric annulus
根据团状流及环状流的流动特性，并考虑同心环形管的结构特徵，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。
