| 摘 要： | 为研究压力容器外部冷却过程中的两相流动和传热现象，采用安全分析中通用的RELAP分析程序对REPEC非加热研究实验进行模拟计算，通过改变体积流量大小、注气方式和进出口面积对自然循环流率和外部冷却两相流动现象进行分析.结果表明，模拟结果与实验结果的一致性较好；循环流量随体积流量的提高呈现先增强后降低的趋势；进出口面积增大可以提高自然循环流量，但出口面积变化对循环流率和流动稳定性的影响更为显著.

| Abstract: | To study the two phase flow boiling phenomena under external reactor vessel cooling(ERVC)condition, the RELAP code was used to simulate the REPEC non-heating experiment.The simulation is mainly focused on the effect of air flow rate,injection distribution and inlet/outlet area on the natural circulation mass flow velocity and flow phenomena.A good agreement is achieved between the simulation results and experimental data.The natural circulation flow velocity increases with the increasing of air flow rate fi... |
