An Evaluation of the Plitt and Lynch & Rao Models for the Hydrocyclones

The Plitt and Lynch & Rao empirical models are widely used for prediction of hydrocyclones performance. In this: work, these models were used to predict the performance of five different hydrocyclones: Rietema, Bradley, DEMCO, Mozley, and AKW. The cut size, the flowrate, and the feed liquid reporting to underflow predicted by Lynch & Rao model showed large errors in comparison with the experimental values. The same has occurred with the Plitt model, apart from the flow rate which showed a reasonable average error (± 13.5%).
