NUMERICAL-MODELS FOR 2-PHASE TURBULENT FLOWS

Numerical models for turbulent fluid-particle flows are reviewed. The two approaches typically used for modeling the dispersed (particle) ph ase are the trajectory and two-fluid formulations, while volume-averag ed models are most common for the continuous (fluid) phase. The review is structured according to the turbulence models used for the continu ous phase: turbulence energy-dissipation models, large-eddy simulation s, direct numerical simulations, and discrete vortex models. The appli cations of these models to simulate particle dispersion due to fluid t urbulence and the adjustments to the models to account for the modulat ion of the carrier phase turbulence by the particles are addressed.
