Numerical Analysis of Cyclone Separator

Abstract

The fluid dynamics of a three-dimensional cyclone separator were studied computationally. Commercial CFD software package, Fluent was used for the simulation. A multiphase Eulerian-Eulerian model incorporating the kinetic theory of granular flow (KTGF) was applied for simulating the air-solid movement. Momentum exchange coefficients were calculated using the Gidaspow drag functions. The kinetic energy fluctuation of mixture was characterized by varying the pressure values from 98Pa to 180Pa. Further computational and modeling efforts are required in a comparable time and space resolutions for the validation of CFD models for Cyclone separator.
