在单相耦合模型的基础上，采用合适的粒子反弹模型和磨损模型，分析、推导、编制了三元粒子运动、碰撞的程序，并通过离心风机叶轮磨损的可视化实验，有力支持了该三元粒子程序的可靠性，为气固两相流离心风机叶轮的研制提供了行之有效的理论工具
Based on the single-phase coupling model, the appropriate particle bouncing model and wear model are used to analyze, derive and compile the program of ternary particle motion and collision. The ternary element is effectively supported by the visual experiment of centrifugal fan impeller wear. The reliability of particle program provides an effective theoretical tool for the development of centrifugal fan impellers of gas-solid two-phase flow
