In this paper the turbulent models for dilute gas-particle flows are briefly reviewed and the problems encountered in the turbulent simulations are discussed. Then we describe the two way coupling Large Eddy Simulations in which the effect of particle existence on subgrid-scale flows have been taken into account. We survey these models based on the comparison of the calculated results of three-dimensional Navier-Stokes equations and the Lagrangian particle motion equations and the experimental data.
