A Reynolds stress model for predicting gas-particle two-phase turbulent flows has been developed in order to take account of the interactions between dispersed particles and fluid turbulence. The effects of dispersed particles on turbulence are added to the Reynolds stress model for single-phase turbulent flows. The model coefficients have been determined by using the experimental data of a gas-particle round jet and a fully-developed vertical pipe flow. The proposed model can satisfactorily reproduce the experimental data of both mean flow and turbulent properties. Finally, the model has been applied to a gas particle two phase turbulent swirling flow in order to investigate the model performance. The predictions show good agreement with the measurements in the case.
