摘要

反应堆集成式堆顶结构的功能之一是通过冷却气体的对流传热为控制棒驱动机构提供冷却。针对ACP100反应堆集成式堆顶结构建立完整的模型并划分流场网格，基于ANSYS/CFX软件分别对可压缩气体和不可压缩气体进行计算，并严格对比分析了其结果，重点研究气体可压缩性对对流传热计算结果的影响。计算结果表明，气体可压缩性对速度、温度分布和压降有较大影响，忽略气体可压缩性所预测的控制棒驱动机构表面最高温度偏低，控制棒驱动机构间隙气体最大流速和压降也偏低。

Abstract

Background

One of the functions of the integrated head package is to cool down control rod drive mechanism (CRDM)

which is realized through convective flow and heat transfer of cooling gas.

Purpose

Concerning the integrated head package of ACP100 nuclear reactor

we rigorously compared the thermal-fluid computation results. The emphasis of numerical simulation and comparison was laid on the effect of gas compressibility on heat transfer of cooling gas.

Methods

The complete mesh model is built by HyperMesh and the thermal-fluid computation results are simulated with commercial ANSYS/CFX software and treating fluid media as both compressible and incompressible gases.

Results

The simulation results show that the gas compressibility has great impact on the distribution of temperature

velocity and pressure fields.

Conclusion

Ignoring the compressibility of gas would give an underestimation of maximum temperature on CRDM surfaces

lower maximum velocity and smaller pressure drop on CRDM gaps.
