摘要
本文通过差压式测量方法,对气液两相流中含气率及油水两相流中含水率的测量进行了深入的试验研究。通过水平及垂直上升段的结构组合,测量气液两相流中的含气率值,在对流型测量与分析的基础上,建立了不同流型下垂直上升段与水平段摩擦压降间的修正关系式,减小了测量误差;通过采用一缓流的垂直下降段,测量油水两相流中的含水率值,获得了好的结果。
In this paper, the experimental investigation on measurement of void fraction in gas-liquid two phase flow and water holdup in oil-water two phase flow are performed using pressure drop method. By the combination of vertical upward section and horizontal section, void fraction in gas-liquid two phase flow is measured. Based on the measurement and analysis to flow patterns, the corrected correlation of frictional pressure drop between vertical upward section and horizontal section is established for different patterns. So the measurement error is decreased. Using a vertical downward section in which flow is very slowly, water holdup in oil-water two phase flow is measured, and a good result is obtained.
