Analysis on Method of ReactorMetal Reflector By-pass Flow

摘要: 金属反射层铁水比高,需要确定其旁流份额,从而优化其结构设计、并为金属反射层温度场计算提供输入。采用计算流体动力学分析(CFD)数值模拟,计算堆内构件金属反射层的旁流份额,并对计算结果进行分析评价,与基于经验公式的分析方法及实验结果进行了对比。通过分析比较得出:CFD数值计算可模拟复杂流道结构,反映流场特征,计算结果有效。

Abstract: The metal is much more than the water for the heavy reflector. By-pass flow should be calculated, which can optimize structure and provide input for the thermal analysis. CFD can be used for analysis the portion of metal reflector by-pass flow, and then results can be analyzed and evaluated. Finally, use the results to comparewith the theoretical analysis and experimental results. The result show that the complex channel and the characteristics of the flow field can be simulated by CFD, results are credible.
