CEFR中间热交换器一次侧数值模拟

Numerical Simulation of Primary Side for Intermediate Heat Exchanger in CEFR

摘要: 应用CFX程序对中国实验快堆（CEFR）一回路中间热交换器（IHX）一次侧的1/6进行三维稳态模拟。计算获得IHX一次侧速度场、换热管束的温度分布及变化规律。结果表明，中间热交换器满足设计要求，能保证主热传输系统的正常工作。计算结果可为快堆调试及运行提供技术支持和理论依据。

Abstract: Using commercial CFX code 3D simulation, the 1/6 primary side of intermediate heat exchanger (IHX) in CEFR was investigated. The temperature distribution, velocity distribution and their change trends of IHX primary side were acquired. The results show that the IHX satisfies design requirement. The results will be technical preparation for commissioning and operation of CEFR.
