| 摘 要： | 气液两相流的流型对其流动和传热特性有很大影响，所以如何确定流型一直是两相流研究中的重要课题。对倾斜下降管内气液两相流流型的鉴别进行了实验研究。结果发现：利用压差的时域信号和信号的功率谱密度函数(PSD)，可以客观地判别流型。

| Abstract: | The flow pattern identification for gas-liquid two-phase flow in a downward inclined tub has been studied experimentally. The result shows that the flow patterns of gas-liquid two-phase flow can be objectively identified in accordance with time domain signals of differential pressure and the power spectrum density (PSD) of corresponding signals. At the same time, we can infer that stratified wave flow is another kind of intermittent flows by analyzing its PSD. |
