摘要
自然循环条件下,UTSG并联倒U型传热管内存在非均匀流动,部分传热管出现倒流,倒流的发生对反应堆自然循环能力产生显著的影响。本文综述了自然循环条件下UTSG非均匀流动研究现状,包括非均匀流动的实验研究、机理分析及数值计算研究。在讨论现有研究存在缺陷的基础上,对进一步的研究提出了一些建议。
For natural circulation, it is shown that parallel flow in the tubes of inverted U-tube team generators can be non-uniform. And reverse flow occurs within some tubes, which can greatly influence the characteristics of natural circulation. Advance in research of non-uniform flow distribution in UTSG under the natural circulation condition is reviewed, including experiment, mechanism analysis, and numerical calculation. According to the analysis on the advantages and disadvantages of those researches, some proposals for the further study are given.
