In this work, fluid flow with particle motion in a miniature cyclone is simulated using a Eulerian-Lagrangian approach. The RNG k-epsilon, linear pressure-strain RSM, and low-Re stress-omega RSM models are investigated to describe air flow. Moreover, the discrete phase model (DPM) is applied to track particle motion. Numerical prediction results are compared with experimental data. The three computational fluid dynamics models are proven suitable to the cyclone body alone without inlet contraction and outlet expansion. However, only the former two models are suitable for full cyclone prediction; they present a typical swirling flow coupled with an incoming jet flow because of their low-Re corrections, thereby yielding a low turbulent viscosity in the impinging region near the wall. Therefore, the DPM with the boundary condition of trap on inlet contraction section and cyclone bottom can track particle motion in a miniature cyclone. (C) 2017 Elsevier B.V. All rights reserved.
