摘要
随着先进核反应堆的研究兴起，两相自然循环系统的稳定性问题受到广泛重视．本文在ＥＩＣＥ算法的基础上发展了数值仿真算法ＡＥＩＣＥ，对两相自然循环系统特性和稳定性进行了分析．分析表明，增大系统压力和增加入口欠热度，均会增大两相自然循环系统的稳定区域．计算结果与实验数据符合得较好．
Accompanied with the development of advanced reactor research, the stability problem becomes more and more important. The AEICE numerical algorithm, which is based on the EICE, is developed in this article. Furthermore, the AEICE is used to analyze system characteristics and thermo-hydrodynamic instabilities of boiling two-phase natural circulation system. It shows that increasing system pressure or inlet subcooling can enlarge the system stability region. The numerical results correspond well with the experimental data.
