摘要: 提出了绕流圆柱压差-涡轮联合测量气液两相流的方法,研究了管内气液两相流的绕流圆柱压差-涡轮流量测量特性。以计算机为检测手段,进行了容积含气率分别为0、0.3、0.5、0.8和1.0两相流工况的测量,在分析实验数据的基础上,建立了气液两相流的绕流圆柱压差-涡轮流量测量方程,获得了气液两相流的绕流圆柱压差-涡轮流量测量方程的特性。

Abstract: The paper puts forward a method of combining round cylinder pressure drop - turbine meter for measuring gas - lipuid flow in a duct. The characteristics of this method were investigated in the experiments. By means of computer control,the performance of the experiments with volume fractions β=0. 0,0. 3,0. 5,0. 8 and 1. 0 was measured. Based on the observation and analysis, an equation for the round cylinder pressure drop - turbine meter measurement was developed. A theoretical discussion of the measurement method was presented.
