abstract

The accuracy of Computational Fluid Dynamics (CFD) simulations of complex flows in general, and highly swirling flows in particular, depends on a number of parameters. In this paper we report on the sensitivity of CFD simulations of transient flow in an automotive reverse flow type cyclone particle separator to mesh size/type, turbulence models, and temporal discretization schemes. More specifically, this study is concerned with the effect of these modeling choices on the two main performance measures of the cyclone: overall pressure drop and particle separation efficiency.
