Comparison of the Three Dimensional Calculation and Experimental Results in Gas Solid Two Phase Flow Centrifugal Fans

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。

In this paper, on the basis of the “one way coupling” model, the three dimensional particle motion and bounce program was established by using appropriate particle bounce and erosion models, and its reliability was strongly supported by the erosion visual experiments in the centrifugal fans. A useful theoretical tool for designing gas solid two phase flow centrigugal fans was given.
