Abstract: Aiming at the cyclone separator′s applicability, the separation efficiency affected by working conditions was studied. The solid particle size and density were selected as environment parameters and the inlet velocity as working parameters. Based on FLUENT, the RNG k ε model and discrete phase model(DPM) were used to simulate the turbulent flow of gas phase and particle trajectory of solid phase respectively in cyclone separator. Because the particle size, density and inlet velocity change respectively will produce a variety of combinations, the orthogonal test method was introduced to reduce the number of simulation. The relationship between the cyclone separator inlet velocity and separation efficiency was discussed under different particle size and density. The results indicate that working parameters of cyclone separator has significant influence on the separation efficiency in different environment.
