应用弯头测量管道中流体的流量早在30年代就开展了这方面的研究工作。这种测量方法的优点不需专用的测量元件,应用被测管道的弯头即可进行测量且不增加流体的流动阻力。至今,在应用弯头测量单相流体流量方面已发表了许多论文。但是,应用这种测量方法测量气液两相流体流量的研究工作几乎尚未开展。本文以水和空气混合物为工质,用页90°弯头进行了气液两相流体流量的函试研究,并在试验基础上用气液两相流体的匀相模型导出了以弯头测量气液两相流体流量和各相组分的计算式。
The application of elbows to measure the flow of fluid in the pipeline as early as the 30s on the research carried out in this area. The advantages of this measurement method do not need a dedicated measuring element, the measured pipe elbow can be measured without increasing the fluid flow resistance. To date, many papers have been published on the measurement of single-phase fluid flow using elbows. However, the research on the measurement of gas-liquid two-phase flow using this method has hardly been developed. In this paper, the water and air mixture as working fluid, the page 90 ° elbow conducted a two-phase gas-liquid flow rate of the pilot study, and on the basis of the experiment using the gas-liquid two-phase fluid phase model derived elbow measurement Gas-liquid two-phase fluid flow and the phase of the formula.
