摘要

建立了稳态两相垂直向上流在圆柱通道内的理论模型。用文献中的实验数据部分地比较了该模型对圆形沟道和重构矩形沟道模型的计算结果。它表明,一般来说,该模型在气泡状态下比段塞流状态下更能预测流动特性,这表明需要进一步研究用于关闭该状态下模型的一些本构关系。

A Fully Developed Two-Phase Flow Model in Vertical Channels for Bubbly and Slug Flow Regimes
A theoretical model for steady state two-phase vertical upward flow in cylindrical channels is presented. A comparison of the results of this model for a circular channel as well as a reformulated rectangular channel model is partially made with experimental data in the literature. It shows that in general the model predicts the flow characteristics somewhat better in the bubbly regime than the slug flow indicating the need to look further into some of the constitutive relationships used to close the model in this regime.
