Design and numerical analysis of a compound hydrocyclone

摘要

The paper determines the structure of the compound hydrocyclone, by using RNG k-ε model for calculation of flow distributor. By utilizing Reynolds Stress Model (RSM) and Discrete Phase Model (DPM), the internal flow fields of the hydrocyclone with different tangents of inlet channels are analyzed and the separation efficiency of the hydrocyclone is calculated. Determining the structure of flow distributor; getting the optimal angle between beveling hydrocyclone with single inlet channel and external surface of ring pipes of distributor; the best beveling angle of inlet channel of beveling hydrocyclone with single inlet channel is 5°.
