摘要

简要介绍了一种新型气液两相流量传感器——槽式孔板的工作原理，在分析两相流体与槽式孔板相互作用机理的基础上，结合实验数据和理论模型详细分析了影响槽式孔板两相压降倍率的各种因素.利用曲面拟合技术给出了能够准确表征槽式孔板两相压降倍率与压力、气体Froude数、Lockhart-Martinelli参数之间的相关式，为凝析天然气计量技术研究奠定了基础.

Abstract

The metering principle of slotted orifice as a new type of flow sensor for gas-liquid two-phase flow is briefly introduced.The interaction mechanism between two-phase flow and slotted orifice was analyzed in detail.Various factors that affected the two-phase multipliers were investigated based on the theoretical model and experimental data.Based on the surface-fitting technique a precise correlation was obtained

which described the relationship among the two-phase multipliers

pressure

gas Froude number and Lockhart-Martinelli parameter.Such information is important for the development of condensate gas meter.
