Abstract
Particle-gas flow in a cyclone separator used in a circulating fluidized-bed boiler is simulated using computational fluid dynamics software Fluent 6.2.36 and an Unsteady Reynolds-Averaged Navier-Stokes (URANS) method. A Lagrangian method is used for particle simulation and a one-way coupling between particles and gas is assumed. The effect of the turbulence model is studied using several turbulence models. Only the Reynolds stress model gives a physically reasonable flow field without adjusting parameters unknown beforehand.
