The numerical simulation of the cyclone separator was carried out by CFD software. The effects of the gas outlet duct length on the pressure drop and separation efficiency were discussed. The gas phase is used as a continuous medium, and the RNG k-ϵ turbulence model is used to simulate the flow field. Using the particle phase as a discrete system, a random orbital model is used to calculate the orbit of the particle based on the calculated flow field. The simulation results show that the flow field in the cyclone separator is anisotropic. When the inlet velocity is constant, the pressure drop of cyclone separators increases with the increase of gas outlet duct length. The longer gas outlet duct can limit the inflowing gas, so that there is enough time to establish uniform rotating flow. It helps stabilize the spiral airflow and improve the separation performance of cyclone separator.
