Abstract: Simulation study on the movement of particles at Lagrangian coordinates in a cyclone separator was made by phase coupling random trajectory model. The results indicate that the movement and separation efficiency of smaller particles are more affected by their inlet position than those of larger ones. Generally, the particles near the outer side of the inlet are easy to separate.
