cyclone;  numerical simulation;  turbulence model;  Discrete mode

The flow field of cyclone separator was studied numerically by using the computational fluid dynamics software FLUENT, using k-ε standard model, RNGk-ε model and RSM model turbulence model and different discrete methods. By comparing the simulation results with the measured results of predecessors, a numerical calculation method suitable for cyclone separator was determined. The results show that the turbulence model adopts the anisotropic RSM model, and the QUICK format of the convection term and the PRETO format of the pressure gradient term are used in the discrete mode, so as to obtain reasonable flow field simulation results. This conclusion provides a reference for the numerical simulation of the flow field of cyclone separator and the further structural optimization design.
