摘要
应用计算软件STAR CD对中国实验快堆 (CEFR)正常运行工况中的额定工况进行了三维数值分析 ,使用多孔介质模型对屏蔽柱的影响进行了模拟 ,给出了冷热钠池的三维温度场和流场 ,与已有热工设计进行了比较 ,并着重分析了浮升力在数值模拟计算中的影响 ,为事故工况下的设备动态分析及相应的设备力学分析提供了数据。研究结果为CEFR的优化设计及事故分析提供了参考数据和技术支持。
The CFD software STAR-CD was used to simulate the normal operating conditions of cold and hot plenums in China Experimental Fast Reactor (CEFR). Complex 3-dimension model was established by using porous medium method. The temperature and velocity distributions of cold and hot plenums were given. These results were compared with the data of the thermal designs of CEFR which had been completed. Meanwhile, the influence of the buoyancy forces was analyzed. The results of the calculation are valuable for the CEFR design and accident analysis.
