Two-phase turbulence models for simulating dense gas–particle flows

摘要: A second-order moment two-phase turbulence model for simulating dense gas-particle flows (USM-� model), combining the unified two- phase dilute with kinetic theory of particle collision, is proposed. The interac- tion between gas and simulated using transport equation velocity correlation a two-time-scale dissipation closure. proposed applied to simulate in horizontal channel downer. Simulation results their compari- son experimental show that accounting both anisotropic particle-parti- cle collision obviously better than models only or particle-particle collision. USM-� also k-e-kp-� k-e-kp-ep-� first can simu- late redistribution Reynolds stress components due inter-particle whereas sec- ond third cannot.
