摘　　要：针对管道的冲蚀磨损问题,基于液固两相流理论及离散相模型,应用Fluent有限元分析软件,建立了排污管道的二维有限元模型。结果表明,含固体颗粒的液体对排污管道产生的冲蚀磨损,主要集中在分支管与总管的交接处。研究方法对排污管道的设计具有一定的参考价值。Aiming at the problem of erosion and wear of pipelines, based on the theory of liquidsolid two-phase flow and discrete phase model, a two-dimensional finite element model of the sewage pipeline was established using finite element analysis software Fluent. The results show that the erosion and abrasion caused by the liquid containing solid particles to the sewage pipe is mainly concentrated at the junction of the branch pipe and the main pipe. The research method has certain reference value for the design of sewage pipes.
