| 摘 要： | 本文以低压空气－水为介质，对子通道内的空泡份额分布进行了实验研究，使用电导探针测量系统测定了子通道内的空泡份额分布。通过实验数据的整理，得到了截面平均空泡份额，并将实验结果与已有的计算截面平均空泡份额的方法进行了比较，在此基础上，讨论了子通道内截面平均空泡份额的计算方法。

| Abstract: | This paper reports the experimental study of void fraction in subchannels of air-water two-phase flow. The distribution of the void fraction in subchannels was measured with electrical probes. The cross-sectional average void fractions in the subchannels were obtained by integrating the local void fractions meastured. The experimental data of the cross-sectional average void fraction in the subchannels were compared with the results calculated by the empirical methods available in the literature. The methods suitable for the calculation of the void fraction in subchannels were discussed. |
