【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。由波状分层流的功率谱密度函数可以推断波状分层流是间歇流的一种表现形式更多还原

【Abstract】 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.更多还原
