| 摘 要： | 对垂直上升管内气液两相流在摇摆状态下和非摇摆状态下分别做了截面含气率的实验研究,发现在水流量较小时,两相流在摇摆状态下的截面含气率小于非摇摆状态下的截面含气率.通过对实验现象的观察和对单相液体在两种状态下摩阻系数的分析,合理解释了产生这种结果的原因.

| Abstract: | Experimental studies on the upward gas-liquid two phase flow under rolling and steady state were carried out respectively.It found that when the volumetric flow rate of water was lesser,the void fraction was lesser under rolling state than under steady state,which was explained reasonably through observing experimental phenomena and analyzing friction coefficient of single-liquid phase under two states. |

| Keywords: | two phase flow rolling void fraction |
