摘要
以空气、水、4 6 # 机油为介质 ,进行了倾斜下降管内油气水三相流流型鉴别的实验研究。实验结果发现 ,利用压差的时域信号和信号的功率谱密度函数 (PSD) ,可以客观的判别流型。
This paper presents a experimental study on flow pattem identifieation in inclined downward oil gas water threephase flow, which unes air,water and 46 # engine oil as the medin. As a result, the time area signal of presure drop and Power Spectrum Density function of signal can identify the flow pattem. It can conclude that stratified wavy flow is a type of intermittent flow by the Power Spectrum Density function of stratified wavy flow.
