Two-fluid large-eddy simulation approach for particle-laden turbulent flows
In this paper, effects of particles on the subgrid scales of turbulence are properly accounted for during the modeling. of subgrid scale stresses in the large-eddy simulation (LES) of fluid phase. In doing so, we propose closed filtered kinetic equations for phase space density of the particle. The various moments of these equations give the 'fluid' equations which can be considered as the LES equations for the particle phase. The influence of subgrid scales motion on the particles is included in these 'fluid' equations.
