abstract

This work presents a computational fluid dynamics (CFD) calculation of gas-solid flow in cyclones with a conventional tangential single inlet (CTSI) and a direct symmetrical spiral inlet (DSSI) which was developed by Zhao et al [1]. The Reynolds stress model (RSM) has been employed to predict the gas flow field and particle paths are calculated with the stochastic Lagrangian model. The calculated grade collection efficiency and pressure drop have reasonable agreement with the experimental data. All results indicate that the DSSI has effect on significantly increasing collection efficiency with insignificantly increasing pressure drop. Compared with the CTSI cyclone, the DSSI cyclone has higher collection efficiency due to larger tangential velocity distribution, less short re-circuiting flow and shorter distance for particles to move to the wall. But the larger tangential velocity distribution lead to a little higher pressure drop of the cyclone with DSSI.
