摘　　要：各类气体中存在工业煤气组分和现场工况复杂等问题,实现准确计量难度较大。本文以高炉煤气为研究方向,探究复杂流场环境中,孔板流量计为代表的差压式流量计测量多组分流体体积流量的实用测量模型与不确定度评定方法。该研究成果可为后续常规流体和简单流场的研究提供参考。There are many problems in various gases,such as industrial gas components and complex field conditions,so it is difficult to achieve accurate measurement.Taking blast furnace gas as the research direction,this paper probes into the practical measurement model and uncertainty evaluation method for measuring volume flow of multi-component fluid with orifice flowmeter as representative of differential pressure flowmeter in complex flow field environment.The research results can provide reference for the follow-up research of conventional fluid and simple flow field.
