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.
