摘　　要：本文采用数值模拟的方法研究了压缩机内固体颗粒对叶片的冲蚀磨损过程。在Ansys软件Fluent中,采用Realizable k-epsilon湍流模型计算气流场。本文通过建立冲蚀模型,从颗粒直径对冲蚀结果进行分析。分析结果表明:当固体颗粒直径在某一范围内时,塑性材料的冲蚀率和固体颗粒直径之间存在线性关系,直径为5,10,15μm的颗粒主要对叶片前缘顶部、腹部、叶片一侧造成磨损,而直径为15μm的粒子对叶片的冲蚀磨损效果最为明显,这就说明直径越大,对叶片的冲蚀率越大。This paper uses numerical simulation to study the erosion and wear process of solid particles on the blades in the compressor. In the Ansys software Fluent, the Realizable k-epsilon turbulence model is used to calculate the airflow field. This article analyzes the erosion results from the particle diameter by establishing an erosion model. The analysis results show that when the diameter of the solid particles is within a certain range, there is a linear relationship between the erosion rate of the plastic material and the diameter of the solid particles. The particles with diameters of 5, 10, and 15 μm mainly affect the tip of the leading edge of the blade and the abdomen of the pressure surface., One side of the blade causes abrasion, and the particles with a diameter of 15μm have the most obvious erosion and abrasion effect on the blade, which means that the larger the diameter, the greater the erosion rate on the blade.
