摘要: 以4号机械油、自来水和空气为实验介质,对水平及微倾斜有机玻璃管内油气水三相流的流型及其转变特性进行了实验研究。采用观察法和流型识别仪相结合的方法,按照油、水两相的关系以及气液界面总体特征,将管内油气水三相流的流型进行了划分,并给出了相应的流型结构及流型图。以实验数据为基础提出了考虑流动参数变化影响的反相点预测关联式。按照现有的关于气液两相流的流型转变准则以及考虑流动条件的油水乳状液的变化规律,对管内油气水三相流各流型之间的相互转变进行了预测和分析,结果表明,气相的作用使油水分布发生了很大变化,不同流动条件下的油水混合物的物性变化也很大。

Abstract: Taking No.46 mechanical oil,air and tap water as working fluids,the flow patterns and their transition property of oilgas-water three-phase flow in the horizontal and slightly inclined pipes were experimentally studied by visualization method and flow pattern identification instrument.The oil-gas-water three-phase flow patterns in the horizontal and slightly inclined pipes system were defined and distinguished by the signals of pressures and pressure differential transducer.According to oil and water distribution in pipes and the total characteristics of gas-liquid interface,the patterns of oil-gas-water three-phase flow were classified,and the flow pattern maps were given.A new correlation for phase fraction of oil-water mixtures was proposed on the basis of experimental data.The transition mechanisms between different flow regimes were analyzed by using the flow patterns transition criterions for traditional gas-liquid two-phase flow combined with different viscosity models developed for different flow conditions.The result shows that the distribution of oil and gas changes greatly under action of air.The property of oil-water mixture changes greatly under different flow conditions.

Key words: oil-gas-water three-phase flow, flow pattern, horizontal pipe, inclined pipe oil-water mixture, phase inversion, experimental study
