Based on the analysis of transportation equation of turbulence fluctuant velocity in the rotating frame of reference, it is the first time that the extended intrinsic mean spin tensor is instead of mean vorticity tensor in the well-known Richardson number and applied to improve the A. Hellsten's correction of system rotation to Menter's kappa - omega SST turbulence model. The modified model is more applicable for turbulence simulation in the rotating frame of reference. It is used for turbulence simulation of flow in the centrifugal pump impeller in this paper. Compared with Menter's kappa - omega SST and original rotation correction, this model can get better result of effect of system rotation and its induced to the turbulence in the centrifugal impeller.
