摘　　要：在含有气团的长输水管道系统中发生的水锤甚至比常规水锤大得多,文章采用水动力学控制方程的一维数学模型,利用特征线方法对管道中高压静水流冲击气团的瞬变过程进行了数值分析,并讨论了气液两相参数对水锤压力的影响。Water hammer in long water pipe with air mass is much larger than normal water hammer. As such, this paper employs one-dimensional mathematical model of hydrodynamic control equation and characteristic line method to conduct numerical analysis on transient process occurring in high-pressure static flow＇ s rush to intercept air mass as well as to discuss the impact of gas-liquid two-phase parameter on water hammer pressure.
