旋风分离器相似特性分析

ANALYSES OF SIMILAR CHARACTERISTIC OF CYCLONE SEPARATOR

模型实验的基础是相似理论,而相似理论的核心问题是相似准则。旋风分离器的流体流动、颗粒运动较为复杂。本文用一简单的方法,导出适合旋风分离器模型实验的准则方程,并具体推导了部分分离效率η_i与准数间的函数关系。

The basis of model experiment is similar principle, and the core problem of similar principle is similar criterion. Since the fluid flow and particle motion inside the cyclon separator were complicated, this paper derived the criterion equations which were applied to model experiment of cyclone separator. The functional relations between partial separative efficiencys and criterions were also derived.
