| 摘 要： | 在倒U型管垂直段的两端内分别放置一个整流环，来消除入口弯头对垂直段流动的影响，通过对单相流体在倒U型管内的流动进行数值计算，以及对整流作用下倒U型管内气液流动的稳定性和流型的分布进行实验研究，发现整流环的整流作用可以增强管道内流动的稳定性，实验还发现，倒U型管垂直上升段内的间歇性流动（弹状流和块状流）区域减小，环状流区域增大，流动的稳定性增强。

| Abstract: | The fairing rings are built in the inlet and outlet of the vertical parts of inverse U bend respectively in order to restrain the effect of bend on the flow in it. By the numerical calculation of single phase flow and the experimental results of two phase flow it is found that the fairing rings can increase the flow stbility of gas liquid flow. The same results are found by the flow pat tern distributions of inverse U bend experimentally. It was found that the intermittent flow region (the region of slug flow and churn flow) of upward flow in vertical inverse U bend is smal ler and the annular region is larger than that in long straight tube. |
