The swirl gas-particle flows at the exit of a small-scale swirl bumer for pulverized-coal furnaces has been simulated using the k-#epsilon#-k_p model, and measured using a phase Doppler particle anemometer (PDPA). The comparison is made between predictions and measurements. The results give the two-phase axial and angential time-averaged and fluctuation velocities, and particle concentration, showing large recirculation zones of gas and particle phases, formed in the near-axis region of the bumer exit, but lwo particle concentration in the recirculation zone. Predictions are in quantitative or qualitative agreement with experiments. Hence, the k-#epsilon#-k_p model can meet the requirements of engineering application.
