摘　　要：采用RNGκ-ε湍流模型,使用Fluent软件,通过定常数值模拟得到不同工况下流量计表面的磨损率分布,分析磨损规律和磨损位置。结果表明:流场中磨损率和DPM质量浓度分布受进口流速和固体颗粒参数设置影响较大。随着进口流速、固体颗粒体积分数和固体颗粒粒径增大,流量计表面磨损率增大,磨损主要集中在喉部入口处,最大磨损率约为1.0×10^(-8)kg/(m^(2)·s)。This paper adopts RNG κ-ε Turbulence model,using Fluent software,obtains the wear rate distribution of flowmeter surface under different working conditions through steady numerical simulation,and analyzes the wear rule and wear position.The results show that the inlet velocity and solid particle parameter settings have a great influence on the wear rate and DPM mass concentration distribution in the flow field.With the increase of inlet flow rate,solid particle volume fraction and solid particle size,the flow meter surface wear rate increases.The wear is mainly concentrated at the entrance of the throat,and the maximum wear rate is about 1.0×10^(-8) kg/(m^(2)·s).
