To deeply understand the particle dispersion and examine the reliability of large eddy simulation (LES) method in two-dimensional gas–solid free shear flows, a particle-laden plane wake flow was numerically investigated. The gas-phase field was solved by using large eddy simulation method, and the particle trajectories were traced in Lagrangian framework based on one-way coupling. The coherent structures...
A k- ε -kp multi-fluid model is stated and adopted to simulate swirling gas-solid two phase flow. A particle-laden flow from a center tube and a swirling air stream from the coaxial annular enter the test section. A series of numerical simulations of the two-phase flow are performed based on 30 µ m, 45 µ m, 60 µ m diameter particles respectively. The results fit well with published experimental data.
