摘要/Abstract

摘要： 以文献中UOC型冷氢箱流体力学实验数据为基础,对所选数值模型进行验证，验证了模型的准确性。以工业操作条件为基础，采用Fluent软件对UOC型冷氢箱流体力学性能进行数值模拟，对混合方箱收缩流道间距及筛孔挡板与方箱间距进行结构优化，并在收缩流道出口处增设挡板。结果表明，优化改进后的冷氢箱性能与基本构型相比，温度分布不均匀度降低了36.8%，压降降低了21 Pa，冷氢箱综合性能得到较大改善。

关键词: 冷氢箱, 数值模拟, 结构优化, 温度分布不均匀度

Abstract: Based on literature experimental data, the numerical model validation was performed and the accuracy of the selected numerical model was verified. Based on industrial operating conditions, Fluent software was used to simulate the hydrodynamic performance of UOC quench box. The structure optimization of the spacing of contractive-type flow passages and the distance between the screen hole baffle and the square box was conducted. In addition, the baffle was added at the exit of contractive-type flow passage. The results showed that the performance of the optimized quench box is better than that of the basic configuration. The temperature distribution unevenness is reduced by 36.8% and the pressure drop is reduced by 21 Pa. The comprehensive performance of the quench box is greatly improved.

Key words: quench box, numerical simulation, structure optimization, temperature distribution unevenness
