Comparison of two-way coupling models for confined turbulent gas-particle jets in flash smelting (Q1267162)

Flow predictions of confined particle-laden gas jets based on three different two-way coupling models of gas-particle turbulent interaction are compared for 50 and 200 \(\mu\)m particles at inlet particle/gas mass fractions from about 0.3-3.0. Attention is focused on the application to fluid dynamic models of flash smelting. Two confined jet experiments and a flash furnace double-entry jet are simulated. We investigate three types of inlet flow: (1) dominant primary (central) velocity; (2) primary and secondary velocities of similar strength; and (3) dominant secondary stream.
