Prediction of the effects of cone tip diameter on the cyclone performance

This technical note presents a computational fluid dynamics (CFD) calculation to predict and to evaluate the effects of cone tip diameter on the collection efficiency and pressure drop of gas cyclones. The simulation was realised using a Reynolds stress model (RSM) for turbulent modelling and discre...
