Abstract

Abstract A method with hybrid scheme is used to simulate turbulent gas-solid flow through sudden expansion pipe. The present developed code introduces good results in view of comparisons with available experimental data. This encourages the authors to extend the theoretical work considering different parameters. The effects of solid-particles on downward turbulent-air flow through the sudden expansion are simulated using Eulerian-Lagrangian approach. Reynolds averaged Navier Stokes equations associated with standard k-ε turbulence model are used with four-way coupling between the two phases. The separation size is discussed under different effects including: particle sizes, mass loading ratios, area ratios and Reynolds numbers. The computational results indicate that the finest particles can increase the separation bubble size.
