Large-Eddy Simulations of Particle-laden Turbulent Jets

Luniewski M., Kotula P., Pozorski J.

TASK Quarterly : scientific bulletin of Academic Computer Centre in Gdansk

2012

Vol. 16, No 1-2

33-51

The work presents an application of Large-Eddy Simulation (LES) for turbulent two-phase flows with dispersed particles. For the simulations of the continuous phase (fluid), an academic, finite volume LES solver was applied and customised. For comparison purposes, also a spectral solver was considered. The LES of fluid was used together with a Lagrangian module for the dispersed phase in the point-particle approximation, including the two-way momentum coupling between the phases. The particle solver has been further developed for parallel computations. The simulations of turbulent, particle-laden round jets were performed. The results for fluid and particle statistics were compared with available reference data.
