Özet

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.
