摘要

针对V锥流量计在测量湿气时产生的虚高问题

提出用V锥流量计的两相流量系数来进行修正。采用节流比为0.75的V锥

在压力为0.10～0.22 MPa、气相流量为100～300 m

·h

、液相流量为0～0.08 m

·h

的实验条件下

研究了Lockhart-Martinelli(L-M)参数、压力及气体密度弗鲁德数对V锥两相流量系数的影响。结果表明

两相流量系数与L-M参数呈良好的线性关系

线性斜率受气体密度弗鲁德数和压力的影响。获得了两相流量系数与L-M参数、气体密度弗鲁德数和压力的拟合关联式

Abstract

The two-phase flow coefficient of a V-cone meter was proposed to correct the “over-reading” produced by measuring the wet gas using the V-cone meter. The experiment was conducted with the V-cone meter with a diameter ratio of 0.75 for air and water. The test pressure ranged from 0.10 MPa to 0.22 MPa

and the gas and liquid mass flow rates were from 100 m

to 300 m

and from 0 to 0.08 m

respectively. The effects of the Lockhart-Martinelli parameter

the operating pressure and the gas densiometric Froude number on the two-phase flow coefficient were investigated. The results show that the two-phase flow coefficient increased linearly with the Lockhart-Martinelli parameter

and the slope of the two-phase flow coef

ficient vs. the Lockhart-Martinelli parameter was affected by the gas densiometric Froude number and the pressure. The correlation between the two-phase flow coefficient and the Lockhart-Martinelli parameter

the gas densiometric Froude number and the pressure was obtained. On the basis of the two-phase flow coefficient

the wet gas model was developed. The relative error of the gas mass flow rate predicted by the model is within ±5.0% at the 95% confidence level.
