Fluent provides a complete range of tools for modeling of phase separation, solids settling, and particle dispersion and classification. Inertial separation using chevrons or cyclonic separators, and filtration systems using filter media can also be modeled.

Pathlines depict the flow through an in-line filter. CFD modeling revealed flow distribution problems and showed how design modifications could improve performance. Courtesy of Parker Pneumatics.

Cyclone-type particle classifier -- particle trajectories and surface pressure distribution -- Particle collection efficiency and critical carryover diameter can be predicted in inertial separators like the cyclone. The system pressure drop, and its response to design changes, can be determined with ease.
