摘要：LES turbulent models were employed to study the gas-solid two phase characteristics in an axial flow cyclone. Predicted data of velocity and pressure distributions of gas phase and the separation efficiency of the dispersed droplets were listed in this paper. The results showed that there are much differences between the LES turbulent model and RANS turbulent models; the velocities of the gas phase depended mostly on the direction of guide vane, and the operating pressure had a great effect on the collection efficiency of nanoparticles in vacuum conditions.
