旋流沉降池流场的CFD分析

Turbulence Numerical Simulation of Hydrocyclone

旋流分离技术是控制暴雨径流污染的一项新兴的污染控制技术。为此,把传统的旋流分离技术和复合流场旋流分离技术结合起来,实现暴雨径流中固态污染物的去除,并将CFD技术应用于旋流沉降池设计,基于Navier-Stokes方程和标准κ-ε紊流模型,依据三维数值模拟的结果,优化与旋流沉降池设计相关的几何参数,使旋流沉降池具有很好的分离效果。

The technology of hydrocyclone and separation is a new method of pollution controlling in rainstorm pollution, this paper using traditional cyclone separation and multiple separating technique wiping off Contamination. The CFD technology was applied to simulate the flow field of the hydrocyclone, based on the standard κ-ε Turbulent mode, the Results of computing and simulating can be used to direct the optimal hydraulic design of the hydrocyclone.
