摘　　要：由于两相流动的复杂性,利用实验测量手段实现两相流的准确测量成为目前研究的热点。在弹状流流型的工况条件下选取了30个实验点,利用新型气液两相流检测装置进行测量实验,结果表明:液相含率测量相对误差在4.3%以内,总流量测量相对误差在1.6%以内,为气液两相流双参数测量研究提供了一种新的思路。Due to the complexity of two-phase flow,the accurate measurement of two-phase flow by means of experimental measurement has become a hot research topic. 30 experimental points are selected under the condition of slug flow,and the measurement experiment is carried out by the new-type detection device of gasliquid two-phase flow. The results show that the relative error of liquid phase fractions is less than 4. 3 %,and the relative error of total flow measurement is less than 1. 6 %. This study provides a new idea for the study of two parameter measurement of gas-liquid two-phase flow.
