| 摘 要： | 本文介绍了由直角弯头连接的竖直管与水平管内淹没与流向反转问题的实验研究，根据实验结果，分析了弯头对淹没与流向反转的影响，将所得实验结果与竖直管的实验结果进行了比较，分析了水平管长度对淹没过程的影响，以及这种管路中淹没消失滞后的问题，采用无因次量对实验数据进行了处理，给出了表达淹没开始点，淹没消失点和全部携带点的关系式。

| Abstract: | In this paper, the experimental research of flooding and flow-reverse in a test loop whicha vertical and a horizontal tube connected by an elbow is introduced. According to the experimental results, the effects of the elbow on flooding and flow-reverse is analyzed. The expertmental results is compared with the results obtained in vertical tubes. The effect of horizontaltube length and hysteresis in deflooding are analyzed. Dimensionless parameters was used indata process. The correlations for predicting the flooding POint, deflooding point, completedcarry up and flow reverse points are given. |
