CFD Prediction of a Cyclone Separator

This paper presents a numerical study of the gas-anthracite particle flow in a tangential cum spiral inlet cyclone separator by increasing the vortex finder length. The pressure and flow field are computed and then used in the determination of particles flow that is simulated by the use of a Discrete Phase Model (DPM) following Euler-Lagrangian model. The efficiency variation of the cyclone separator is shown in terms of collection efficiency and trajectories of particles from the simulation. The effects of particle size, density and vortex finder length on the collection efficiency are quantified.
