Abstract: K-ε-Kp model is adopted to numerically simulate the gas-particle two phase flow of a pulverized coal burner. The results of calculation and experiment show that the axial velocity profile has negative velocity in the internal recirculation zone, the tangential velocity profile possesses the feature of Rankin vortex. The comparison of prediction with experiments show that the K-ε-Kp model is very good agree to those measured in quantitatively and qualitatively. All of these specify that K-ε-Kp model can be used for engineering, but needed to be further improved.
