ABSTRAKT

A gas-particle turbulent channel flow is simulated using a large eddy simulation coupled with Lagrangian particle tracking. A turbulent channel flow at Reτ = 644, loaded with 70µm copper particles at a mass fraction of 2%, is considered and influences of the increase of drag coefficient near the wall on the statistics of particles are investigated. Three different types of coupling mechanisms, two different drag coefficients and two different boundary conditions are examined. The accumulated statistics are compared with the experimental data by Kulick et al. (1994). The statistics computed by the simulation with both wall correction and inter-particle collisions are found to be closer to the experimental data, as compared to statistics from typical conventional simulations which neglect those effects.
