摘　　要：为解决燃气弯管冲蚀失效问题,利用FLUENT仿真软件,采用DPM离散相模型、Forder壁面反弹模型及RNG k-ε湍流模型进行模拟仿真计算,并研究固体颗粒撞击点、冲击角度与冲蚀磨损区域间的规律。结果表明,颗粒含量、粒径、弯管角度、气体流速等影响因子中,气体流速以及颗粒含量对冲蚀率的影响较为显著,同时冲蚀严重区域受弯管角度与气体流速影响较大。For the erosion failure of gas elbow,DPM discrete model,Forder particle wall bounce model and RNG k-εturbulence model were used for simulation calculation by FLUENT simulation software.The law between impact point,impact Angle and erosion area of solid particles was studied.The results show that among the influencing factors,such as particle content,particle size,elbow angle and gas velocity,the gas velocity and particle content have significant effects on erosion rate,and the elbow angle and gas velocity have significant effects on erosion rate in the area with serious erosion.
