| 摘 要： | 针对自然循环工况下蒸汽发生器部分倒U型传热管存在倒流现象，利用CFD软件对倒U型传热管内单相水流动传热特性进行研究。通过建立不同管长的倒U型管水动力曲线，分析了管长对倒流的影响，得出长管处易发生倒流的结论；通过对长管重位压降和摩擦压降随雷诺数变化情况进行分析，对倒流现象的出现进行了的理论解释。该文所得结果对倒流管空间分布的研究具有一定的意义。 |

| Abstract: | Aiming at that parallel flow in the inverted tubes of steam generators (SG) can be non-uniform with natural circulation. The reverse flow of single phase water in inverted U-Tubes of SG was investigated with CFD code. The characteristic curves of flow in parallel U-Tubes are established, and the influence of the U-Tubes length on reverse flow was studied. And the theoretical analyses of the reverse flow have done. The conclusions are very important to the study of the space distribution of reverse flow tube. |
