摘要
大落差管道在运动中，其下坡段可能出现不满流管段。运用两相流基本方程，对管道下坡不满流管段的瞬变流动特性进行了分析；通过水击波传播速度及特征线方程的建立，给出了不满流管的水击分析方法；并通过算例说明本文模型较之于集中空穴模型更符合不满流管段的实际情况。
Slack line flow sessions can appear in a long slope pipeline. The existence of slack line flow like this can change the pipeline flow from single phase to two phase. The paper applies basic equations of two-phase flow to analyse the transient flow characteristic of the slope pipeline. The surge analysis method for such pipeline session is developed form the surge wave velocity and charateristic equation. The example calculation illustrates that the model is superior to concentrative cavitation model in simulation with the actual condition of slack line flow pipeline session.
