摘要
利用改进后的段塞流跟踪模型,对水平管气量瞬变空气-水段塞流场中的压力波传播特性进行了模拟研究,主要分析了压力波沿管线的变化规律以及入口初始液相流量和气相流量的变化对压力波速的影响,并将模型模拟结果与长380m、内径80mm的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;压力波速沿管线具有衰减特性;在气量增加过程中,增压波速沿管线的衰减速率逐渐降低。
<abstract>opagation characteristics of pressure wave in horizontal air-water slug flow field with transient air flow rate are investigated using improved slug flow tracking model. The variation rule of the pressure wave along the pipeline, and influence of the variation of initial inlet liquid flow rate and gas flow rate on the propagation speed of the pressure wave are analyzed. The model simulating results were compared with the experimental ones made on large-scale multiple phase flow channel with 380m long and 80mm inner diameter. The results indicated that the model can effectively simulate the propagation characteristics of pressure wave in slug flow field with transient air flow rate, that the propagation speed of the pressure wave will be attenuated along the pipeline, and that the attenuation rate of the propagation speed of the boost pressure wave in increasing gas flow rate will decrease along the pipeline.
