A Large Eddy Simulation approach for Eulerian-Eulerian dispersed two-phase flow is presented. It is shown that not only the Random Uncorrelated Motion but also Sub-Grid Scales term modeling the unresolved field in the particle mesoscopic momentum transport equation and the particle Random Uncorrelated Energy need to be accounted for. Simulations of a non-homogeneous particle laden turbulent gas flow allow to compare dispersed phase quantities such as number density, time-averaged and rms mesoscopic velocity, fluid-particle correlations with experimental results.
