摘要

摘要: 为了开发压水堆螺旋燃料组件(HCF)的子通道程序，本研究将HCF的阻力模型和传热模型引入COBRA-TF程序，通过两组动量方程预测第一类棒间隙的双向交混和第二类棒间隙的单向交混，通过实验数据和数值模拟结果对新程序的准确性进行验证，对HCF的轴向壁面温度分布、质量通量分布等展开分析。研究结果表明，新程序可准确预测HCF的热工参数分布，并且可用于大规模燃料组件的计算和分析。本研究为HCF的优化设计和工程应用提供了可靠的分析工具。

Abstract: In order to develop the sub-channel code for the helical cruciform fuel (HCF) assembly of PWR, the frictional model and heat transfer model of the HCF assembly is introduced into the COBRA-TF code, the two-way mixing of the first type of rod gap and the one-way mixing of the second type of rod gap is predicted by two groups of momentum equations, the accuracy of new code is validated with the experimental data and numerical simulation results, and the axial distribution of the wall temperature, the mass flux distribution et al. of the HCF assembly are analyzed. According to the study results, the distribution of the thermal-hydraulic parameters of the HCF assembly can be accurately predicted by the new code, and the new code can be used for the calculation and analysis of the large-scale fuel assembly. This study provides a reliable analysis tool for the development and application of the HCF assembly.
