Turbulence-Model and Parcel-Approach Effects in Particle-Laden Swirling Flow
A CFD study of dispersed two-phase swirling flow that quantifies how the choice of turbulence closure and particle-representation strategy affect predictions. Comparing standard, RNG, and realizable k-epsilon models against experiment, it finds the standard model most accurate, and shows that grouping similar particles into parcels cuts computational cost while preserving accuracy in an Eulerian-Lagrangian, two-way-coupled simulation.
