CFD Simulation Of The Flow Field In A Uniflow Cyclone Separator

A numerical analysis of the turbulent and strongly swirling flow field of a uniflow cyclone and its performances is described. The gas flow is obtained by the use of the Reynolds stress model while, the determination of particle flow is ensured by the use of a Stochastic Lagrangian model. The flow features are examined in terms of tangential, axial and radial velocities, pressure drop and separation efficiency. The validity of the proposed approach is verified in terms of cyclone separator performances by the good agreement between the measured and the predicted results.
