摘要：
The gas-solid two-phase turbulent plane jet flow with high Reynolds number of 4500 was numerical investigated by means of lattice Boltzmann method (LBM). The multiple relaxation time (MRT) was employed to deal with the high Reynolds number fluid flows, and the particles were traced by the Lagrangian method. The results show that the flow changes from initial symmetric mode to asymmetric mode with the development of the flow. And asymmetric pattern appears first at the position of x/d = 4, where the vortex structures begin to form. The dispersion of particles at different Stokes number shows various distributions. The MRT-LBM shows its good ability in simulating turbulent flow with the high Reynolds number. (C) 2015 Elsevier Inc. All rights reserved.
