| Abstract: | Following the discussion of two methods for particle trajectory visualization, numerical simulation with Reynolds stress model and particle trajectory model is made to calculate gas-solid twophase flow fields in a centrifugal fan. Moving trajectories of particles of different diameters in the fan are visualized exactly, and the effects of particle diameters on the trajectory are analyzed, which serves as the basis for the investigation of fan abrasion. |
