针对轴流式分离器的冲蚀磨损问题，采用Realizable k-ε模型模拟轴流式分离器内气、固两相的流动情况，并结合Oka冲蚀方程研究轴流式分离器冲蚀磨损失效机理，获得冲蚀磨损速率分布规律。结果表明：含尘气流经过旋转叶片区域时做强扭转运动，气流中的固体颗粒受离心力作用，撞击扭转叶片和筒体，导致扭转叶片局部以及筒体内壁面出现明显的螺旋形冲蚀带。
Abstract：In order to solve the erosion wear problem of axial flow separator, Realizable k-ε model was used to simulate the flow of gas and solid in axial flow separator. Combined with Oka erosion equation, the erosion wear failure mechanism of axial flow separator was studied, and the erosion wear rate distribution law was obtained. The results show that the dust-bearing air flow through the rotating blade area has strong torsional motion, and the solid particles in the air flow are affected by the centrifugal force, impact on twisted blades and cylinder which leads to the obvious spiral erosion belt in the part of the torsional blade and the inner wall of the cylinder.
