沸腾两相自然循环系统中流动不稳定性的研究已经进行了几十年。本文对这方面的研究进行了回顾和总结，对当前和未来的自然循环堆芯冷却轻水堆的设计和安全有一定的参考价值。为此，对沸腾自然循环系统中的流动不稳定性进行了综述。本文试图对自然循环系统中发生的不稳定性进行分类，这与强迫对流沸腾系统中发生的不稳定性相似。在此基础上解释了两相自然循环系统不稳定性产生的机理。综述了各种不稳定性的特点以及不同操作参数和几何参数对它们的影响。
Several decades have been spent on the study of flow instabilities in boiling two-phase natural circulation systems. It is felt to have a review and summarize the state-of-the-art research carried out in this area, which would be quite useful to the design and safety of current and future light water reactors with natural circulation core cooling. With that purpose, a review of flow instabilities in boiling natural circulation systems has been carried out. An attempt has been made to classify the instabilities occurring in natural circulation systems similar to that in forced convection boiling systems. The mechanism of instabilities occurring in two-phase natural circulation systems have been explained based on these classifications. The characteristics of different instabilities as well as the effects of different operating and geometric parameters on them have been reviewed.
