Performances of several
turbulence models in Computational Fluid Dynamics (CFD) simulations of cyclone
separators were evaluated in this study, as a preliminary step to a more
comprehensive modeling work. The models were evaluated using experimental data,
namely pressure drop and cut diameter. Three turbulence models were employed in
CFD simulations: κ-ε model, κ-ω model, and Reynolds Stress Model (RSM). For all
models, the discrepancies between the experimental and simulated pressure drops
were lower than 11%, while the discrepancies between cut diameters range from 1.57%
to 30.5%. Of all turbulence models, RSM proved to be the one that simulates
complex flow properties within cyclone separators. Reynolds Stress Model should
be used as the turbulence model for simulating cyclone separators using CFD.
