溢流口结构对旋流器溢流分率影响的模拟及实验研究

Study of Simulation and Experiment about Influence of Overflow Pipe’s Structure on Overflow Ratio of Hydrocyclones

旋流器的溢流分率是旋流分离过程中的一个重要的操作参数同时也是一个重要的性能参数,文献表明溢流分率对于分离效率有着显著的影响。利用CFD软件Fluent模拟了3种入口条件下溢流口结构对旋流器溢流分率的影响,并根据不同的物理模型进行了实验验证,证明RSM湍流模型在模拟旋流器流场的应用中具有较好的可靠性。

Hydrocyclone overflow ratio is an important operation parameter and of course an important performance parameter, which has marked influence on separation performance of hydrocyclone. This article talks about a numerical simulation and experimental study on the different overflow pipes＇ influence upon overflow ratio.
