循环水系统两相瞬变流计算

The Calculation of the Two Phase Transient Flow in the Circulating Water System of a Power Plant

针对泵系统由于突然失电出现的两相瞬变流的计算，提出了含有气体释放的蒸汽穴模型，以计算释放气体分布整个管线且波速是变化的情况。

In the circulating water system of a thermal power plant or a nuclear power station, there will appear low pressure transient owing to the failure of pump power supply. As the position of the condensers is normally rather high, air release and water column separation in condensers or the pipeline may occur. A mathematical model is developed to calculate the two phase transient flow and has been used in actual calculation. It is suitable for cases where air release and water column separation are taking place in a pipeline and the wave speeds are variable.
