在室温及常压条件下以空气-水为工质,对AP1000稳压器不同液位下的波动管内液泛过程及液泛特征点进行了试验现象研究、机理分析和数据分析,得到两相逆流液泛动态特性。研究结果表明:波动管竖直管部分是最容易发生液泛现象的位置;波动管内液泛特性符合Kutateladze关系式;当气体流量较小时,液相流量随着稳压器液位的增高而减小;当气体流量较大时,液相流量随着稳压器液位的增高而增大;液体完全滞止点基本与稳压器液位高度无关。
At room temperature and atmospheric pressure with air-water as working fluid, the liquid phenomenon and the liquid pan-pan in the fluctuating tube under different liquid level of AP1000 were studied, the mechanism analysis and data analysis were carried out to obtain two phases Countercurrent flooding dynamics. The results show that the vertical tube part of the wave tube is the most prone to liquid pan phenomenon. The liquid pan characteristic in the wave tube accords with the Kutateladze relation. When the gas flow rate is small, the liquid flow rate decreases with the increase of the liquid level When the gas flow rate is larger, the liquid flow rate increases with the increase of the liquid level of the regulator. The complete stagnation point of the liquid basically has nothing to do with the height of the regulator.
