摘　　要：为了获得浙江省多气源混合天然气管网中未安装气质测定设备的那些地方的有关气质信息,以各管道供气入口测定的气质数据为基础,利用流体仿真软件Fluent,以浙江省天然气一期主干线线路管网规划图为依据,建立大规模长输管道管网仿真模型,采用二维单精度解算器、标准k-ε湍流模拟方程、压力基密度求解器和组分输运(species transport)模型,对管网中天然气混合情况进行稳态模拟计算,获得管网出口天然气各组分的质量分数,取仿真结果与实测采集到的数据进行比对,为安装气质测定设备———气相色谱仪的布点提供了依据.To get the information of natural gas composition in multi-gas sources mixed pipeline network where gas composition testers are not installed in Zhejiang province,a steady state simulation was conducted.The simulation was based on the gas composition data from all gas supply inlets by using a fluid simulation software—Fluent with the first stage natural gas main line network in Zhejiang Province.A 2D pressure based solver,a standard k-ε turbulence model and a species and reaction transport model were used in the steady simulation.The analysis of the results showed that the mass fraction of mixed natural gas agreeed well with the actual analysis.This study provides a basis for the installation of a gas composition tester—gas chromatograph.
