Abstract

This paper discusses theoretical and numerical issues that are relevant to computational calculations of cyclone separators. The importance of satisfactory predictions of gas velocities, of an adequate particle stochastic model and of a consistent numerical scheme is stressed. Numerical exemples are provided for two Stairmand-type cyclones and two different kind of particles to illustrate these various points.
