摘要: 对3×3布置压水堆堆芯燃料棒束内冷却剂湍流流场进行模拟,选取ANSYS CFX软件中SST、SSG-RSM、BSL-RSM以及ω-RSM等湍流模型进行稳态模拟,通过与激光多普勒测速仪(LDV)实验数据对比,评价了以上各湍流模型的性能。结果表明,BSL-RSM和SSG-RSM模型的模拟结果与实验结果吻合较好,但在湍流脉动的预测上仍有一定误差。

Abstract: In this paper, the flow characteristics throughout a PWR 3x3 rod bundles was investigated, and four turbulence models including SST,SSG-RSM,BSL-RSM and ω-RSM were used to simulate in steady state and then evaluated with the laser Doppler measurement data of the flow. The comparisons demonstrate that BSL-RSM and SSG perform better relatively though still having some errors in predicting the turbulent fluctuation.
