Reassessment of eddy viscosity turbulence models as alternatives to Reynolds stress models for gas cyclone separator CFD simulations
This CFD study compared multiple turbulence models against experimental data for a 0.29 m Stairmand cyclone. Appropriate discretisation improved some EVMs, and realizable k-epsilon with curvature correction matched linear/quadratic pressure-strain RSM mean-flow accuracy under the studied conditions with less computation. It challenges routine RSM preference but does not cover every cyclone or particle regime.
