Opis:: 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.

Opis:: It is shown, using analytical methodologies, that the velocity field blow-up suffered by vertically ascending acoustic waves in an isothermal atmosphere can be eliminated via the introduction of fine particles. Assuming the inhomogeneous generalization of the particle-laden flow model known as the (linearized) Marble–Thompson model-1, it is established that bounded, exponentially decreasing, shock amplitudes can be obtained provided the mass fraction of particles exceeds a critical value, for which an exact expression is derived. Lastly, supporting numerical results are presented, special cases are discussed, and possible follow-on studies are noted.
