为研究气液两相流的流型变换规律,建立高计算精度的气液两相流水力计算模型,以Shoham和Kokal 的实验数据为基础,对通用流型判别法、改进的Taitel-Dukler 流型判别法及段塞流特征分析法用于气液两相流流型判别的效果进行验证。基于以上3 种判别方法,给出流型判别图,并与实验数据进行对比,总结出3 种判别方法的特点。结果 表明:通用流型判别法和段塞流特征分析法对气液两相流流型的判别结果较好,其中通用流型判别法的计算适用性更强,研究成果为气液两相流水力计算提供了流型判别算法的选取依据。(图2表1,参[21]

In order to study the flow-pattern transition laws of gas-liquid two-phase flow and establish the gas-liquid hydraulic calculation model with high precision, three flow-pattern-prediction models, i.e. the general model, the modified Taitel-Dukler model and the slug characteristic analysis model, were introduced, and their application effects to predict the flow pattern of gas-liquid tow-phase flow were verified based on the experimental data from Shoham and Kokal. Then, based on these three flow-pattern-prediction models, the flow pattern prediction maps were plotted and compared with the experimental data. Finally, the characteristics of the three models were summarized. It is shown that the unified flow-pattern-prediction model and the model via slug characteristic analysis do better in the flow pattern prediction of gas-liquid two-phase flow and the unified model is more applicable to different situations. The research results provide the basis for selecting the flow pattern prediction algorithm used for the hydraulic calculation of gas-liquid two-phase flow. (2 Figures, 1 Table, 21 References)
