| 摘 要： | 采用电导探针在133 m长水平管道上对空气-水段塞流的液塞参数演化特征进行了实验研究,得到了液塞长度、频率统计分布沿管道的变化规律。实验观察到最小稳定液塞长度大约为15D,提出了新的长气泡尾流效应关联式。采用改进的跟踪模型研究了液塞长度等参数沿管演化过程,模型中采用了提出的尾流效应关联式,管道入口液塞长度随机变化。验证表明,模型较好预测出平均液塞长度、最大液塞长度、平均液塞频率等参数。

| Abstract: | Experiments were performed in a 133 m long horizontal test loop to study the evolution of liquid slug parameters.The statistical distributions of slug lengths and frequencies were measured by conductivity probes.The results show that the minimum stable liquid slug length is about 15D and a new correlation of wake effect of elongated bubble was presented.A slug tracking model was adapted to study the evolution of the liquid slug lengths and frequencies.In the present model,the new correlation of wake effect ... |
