Density wave theory
密度波理論
This theoretic model employs the basic idea of correlation measurement , achieve the density wave speed by the correlation of the signals of upper and lower sensors , and get the total flow rate and water cut through the theoretic relationship of density wave speed and total flow rate as well as holdup with the help of drift flux model so as to accomplish the oil / water two - phase flow measurement at last , using the limited available experiment data , the theoretic model has been simplified into an applicable linear alternative which is suitable to homogeneous oil / water two - phase flow measurement to accomplish the oil / water two - phase flow measurement using the density wave phenomena is of highly theoretically valuable for density wave theory research as well as oilavater two - phase flow measurement research . to develop new type oil / water two - phase flow instrumentation based on this theoretic measurement method will be very applicable and promising
在此基礎(chǔ)上，針對穩(wěn)態(tài)密度波理論提出了基于密度波理論的油水兩相流測量理論模型，該模型以密度波傳播理論作為基礎(chǔ)，通過上下游傳感器信號相關(guān)獲得密度波傳播速度，利用密度波傳播速度與總流量以及持相率的理論關(guān)系結(jié)合漂移模型來求解總流量和含相率，實現(xiàn)油水兩相流的測量，在理論分析的基礎(chǔ)上，在實驗資料有限的條件下，對基于密度波理論的油水兩相流測量理論模型作了極限的簡化，提出了本文油水兩相流測量理論方法應(yīng)用在測量均勻油水兩相流中的實用線性模型。
Firstly , flow patterns which related with the characteristics of measurement have been studied with both the time series analysis and density wave theory , which lay a solid foundation for oilavater two - phase flow measurement then a theoretic model of oil / water two - phase flow measurement based on stationary density wave theory has been brought up
論文首先研究了與測量特性有關(guān)的油水兩相流流型問題，基于時間序列分析和密度波理論分別得到了流型表征結(jié)論，為進一步從測量的時間序列波動信號辨識流型奠定了方法基礎(chǔ)。
