CFD-DDPM coupled with an agglomeration model for simulation of highly loaded large-scale cyclones: Sensitivity analysis of sub-models and model parameters

The Dense Discrete Phase Model coupled with an agglomeration model is developed and validated for the simulation of industrial cyclones high solid loads. performance influenced by sub-models, parameters, numerical parameters. To optimize present CFD model, extensive sensitivity analysis was performed, varying one sub-model or parameter at a time, systematically assessing effect on results through comparisons measured pressure drop separation efficiency highly loaded pilot-scale cyclone. investigation shows that turbulence particle-particle restitution coefficient have strongest influence. This study concludes recommendation set parameters providing best prediction hydrodynamics large-scale cyclones. In addition, impact some operating conditions cyclone were examined.
