摘　　要：采用汽泡尺寸概率密度函数(PDF)分析的方法,研究了探测点径向位置对流型识别的影响。结果表明,受热工况下该影响不可忽视。考虑到探测点空间位置对受热工况流型识别的影响,同时为了简化测量与分析,本文提出了“两点判别法”。实验结果表明,该方法对于垂直受热圆管可以得出准确的流型识别结果。Flow regimes identification by statistical analysis of bubble size was applied, and the influence of spatial probe point on flow regimes identification was analyzed in this experiment. The experimental results show that this influence should not be ignored for heated state. In view of this situation the Two Spatial Points Method was provided to simplify the identification in this paper. And the experimental results also show that flow regimes can be identified correctly by this method.
