摘　　要：利用改进后的段塞流跟踪模型对水平管道气量瞬变空气 水段塞流场中的压力波传播特性进行了模拟研究,分析了压力波沿管道的变化规律以及入口初始液相流量和气相流量的变化量对压力波速的影响,并将模型模拟结果与大型多相流试验环道上的试验结果进行了比较。结果表明,该模型能够有效地模拟气量瞬变段塞流场中压力波的传播特性;压力波速沿管道具有衰减特性;气量增加过程中的增压波速沿管道的衰减速率是逐渐降低的。The propagation characteristics of pressure wave in gas flowrate transient air-water slug flow is firstly investigated by improved slug tracking model. The development tendency of pressure wave along the pipe line and the efficiency which liquid flowrate and the variation of gas flowrate affect the speeds of pressure wave propagation are primarily analyzed. And the model results are compared to the experimental ones,whichare gained in 380 m long,80 mm i. d. horizontal stainless steel pipeline. The results indicate that the model can effectively simulate the propagation characteristics of gas flowrate transient pressure wave,that the speeds of pressure wave propagation will be attenuated along the pipeline, and that the attenuation velocity of the speeds of pressure wave propagation in gas flowrate increasing slug flow will decrease along the pipeline.
