CFD modelling was used to simulate particle
segregation in a transverse plane of a rotating cylinder
under different particle-particle drag models. The
Eulerian method was used to model the dense particulate
phases in the system. Two types of particles, with
different density and size, were used in the study. The
simulations were performed under the rolling mode
since this mode is believed to give good particle-particle
mixing. The drag models of Schiller-Naumann, Morsi-
Alexander and Syamlal-O’Brien Symmetric were
applied in the modelling of particle-particle drag and
results were compared with experiments. All the drag
models were able to model the particle segregation. The
Schiller-Naumann model and the Morsi-Alexander
model showed good agreement with the experimental
results while the Syamlal-O’Brien-Symmetric model
had some deviations.
