摘要
流型判别是气液两相流研究的重要内容。应用适用于工业设计中大管径、高压力管道的多相流瞬态模拟软件OLGA,以空气-水为介质,对倾角为-70°～90°、内径为200mm、压力为2.0MPa的气液两相管流进行数值模拟,通过变换不同的气液相流量和管道倾角,研究管道内气液两相流体流型的变化。根据数值模拟所得到的1628组数据,结合流体物性和管道倾角,回归建立了不同流型转变的判别准则经验相关式,为现场大管径、高压力气液两相流管道的流型判别提供了参考依据。
Flow pattern identification is significant in the research of gas-liquid two phase flow. Applied with OLGA, a transient multiphase flow simulation software used in the industrial design of the high-pressure large-diameter pipeline, numerical simulation on a gas-liquid two phase flow is performed, in which gas and water are used as transmission media. The inner diameter of the pipeline is 200 mm and the pressure is set as 2.0 MPa. The pipeline inclination ranges from -70°to 90°. Based on the variety of the gas/liquid flowrate and the pipeline inclination, the gas/liquid flow pattern transition is studied. According to the 1 628 sets of simulation results, taking into account the fluid property and pipeline inclination, empirical correlations on flow pattern transition are established, which provides a reference to the flow pattern identification for high-pressure large-diameter gas/liquid flow pipelines. （4 Figures, 23 References）
