气固两相流风机的三元计算与二元计算的比较

The Comparision of Three Dimensional Calculation and Two Dimensional Calculation 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，并与二元粒子程序进行了比较，验证了该三元程序的优越性，为气固两相流离心风机叶轮的研制提供了一个行之有效的理论工具。

In this paper, on the basis of 'one way coupling' model, the three dimensional particle motion & bounce program were created by using appropriate particle bounce & erosion models, and it was compared with the two dimensional particle program in order to prove its advantages. An useful theorecal tool of designing gas solid two phase flow centrifagal fans was given.
