| Abstract: | Particle tracking method is used to simulate inner flowing of the cyclone separators under Lagrange coordinate system with FLUENT random track model.Analysis is made on the effect on velocity field and separating performance when digging angle and outer cylinder diameter of the cyclone separator changes.Theoretical bases are therefore provided for the structural design of cyclone separator. |
