Multiphase CFD simulations of dense medium and classifying hydrocyclones

Cyclones are widely used in the mineral processing industry to classify and concentrate mineral particle slurries. CFD simulations of dense medium and classifying cyclones have been conducted using FLUENT. The simulations use a three dimensional grid and the Reynolds Stress Turbulence Model. Classification and medium segregation and the air core are being modelled with the Algebraic Slip Mixture Model. The results are compared with density profiles from gamma ray tomography and plant classification data.
