Evaluation of hydrocyclone models for practical ...
2000-12-1 However, models can still be a good tool for estimating hydrocyclone performance as long as the models are applied in the right domain. It is recommended based on the results of this work that some data should be obtained to select an appropriate model for calculations. Any model predictions without experimental data should be treated cautiously.

A model for performance prediction of hydrocyclones ...
2001-9-15 In this work, data obtained with seven hydrocyclones was used to generate a model based on dimensionless groups capable to predict performance of hydrocyclones. Unlike other models that can be found in the literature, where the parameters have to be adjusted for each data set, the proposed model was able to reproduce data from the classical works of Rietema, Bradley and Kelsall.

Mathematical model of the hydrocyclone based on
A mathematical model of the hydrocyclone, based on the physics of fluid flow, has been developed. The model equations are solved in a computer code that takes as input the hydrocyclone dimensions and feed slurry characteristics. The output of the computer code is the velocity profiles of the fluid and the separation efficiency curve.

Optimizing hydrocyclone design using advanced CFD
The particle recovery curve from the CFD model shows good agreement with the actual hydrocyclone performance measured in a controlled test. The CFD model predictions to different vortex finder sizes and the addition of other hydrocyclone geometry changes have also been in the correct direction and magnitude based on validation test results.
