摘要
全面系统地分析和讨论了导致汽液两相流中环状流转变的多种机理及各因素的影响,建立了相应的数学描述方程,并导出了转变判别准则式;指出了各种管道及流动条件下环状流转变的主要控制机理,并将理论与实验数据进行了比较,两者相符很好。
In this paper, various kinds mechanisms of transitions from two-phase annular flow in tubes were studied and moddelled, and the affection factors on the transitions were also discussed. Some mathematical equations and transition criteria for every mechanisms presented were derived, and an unified general criterion for the annular flow transitions in whole range of pipe inclinations was recommended. The boundaries predicted show good agreement with the air-water two-phase experimental data.
