| Abstract: | With the help of CFD software and using a model of particle tracks,a swirling blade type pulverized coal concentrator is being numerically simulated and the concentrator's resistance coefficient,as well as its separation effect,under various modes of operation analyzed.Simulation results indicate that the concentrator studied can both attain a rather good concentration efficacy and a dense-to lean-flow ratio. |
