液膜的流动、分叉和溪流等物理过程与核电站安全壳非能动冷却系统(PCCS)等诸多实际工程问题密切相关,近来备受研究者的关注。文章针对AP600的PCCS液膜流动问题,利用数值方法计算液膜破裂对覆盖率的影响。采用一维欧拉液膜模型计算PCCS液膜流动,并利用EI-Genk和Saber模型模拟液膜破裂过程。结果表明,PCCS液膜厚度在装置顶部变化较大,容易发生液膜破裂和溪流。通过研究液膜覆盖率与PCCS流量的关系,给出了符合安全标准的流量。
Physical processes of liquid film, such as flow, breakup, and rivulets, are closely related to lots of practical engineering issues such as the passive containment cooling systems (PCCS) of nuclear power.Researchers have been paying more and more attentions on these physical processes recently. As for the PCCS liquid film flow of AP600, the numerical methods were applied in this paper to calculate the influences of liquid film breakup on coverage rate. In this study, the one-dimensional Eulerian liquid film model was adopted to calculate the PCCS liquid film flow, and the EI-Genk and Saber models were adopted to simulate the liquid film breakup process. The results show that the thickness of the PCCS liquid film varies a lot at the upper dome of the facility, which could easily induce liquid film breakup and rivulets. By studying the relationship between liquid film coverage and PCCS flow rate, the flow rate meeting safety standards is obtained.
