Abstract
In this study, results are presented of a CFD study on the performance of a Stairmand-type cyclone. The CFD simulations were performed on the basis of the Reynolds stress turbulence model. In spite of three-dimensional flow phenomena, especially in the annulus between the cyclone wall and exit pipe, a large similarity was found between axisymmetric (2D) and 3D simulations of the flow field. The CFD results were compared to experimental data obtained by means of Laser-Doppler Velocimetry. A good correspondence was found between predicted and measured radial profiles of the mean and fluctuating velocity components. Axisymmetric simulations were performed to study the effect of the Reynolds number on the cyclone pressure loss and on the collection efficiency. Grade efficiency curves were obtained by tracking computational particles through the flow domain. The results are compared with correlations from the literature.
