Summary:Floating ring bearings (FRBs) are widely used in the high speed turbocharger for their robustness. This paper introduces a CFD calculation method to predict the performance of the FRBs. Two phase model is included in the calculation method and transit calculation with mesh motion is conducted to predict the vibration characteristics. The simulation results are compared with the experiment to validate this method. Results show the two phase effect is important in predicting the FRBs at low oil-supplied pressure. This method shows great capacity of predicting the ring-to-shaft speed ratio and the vibration characteristics.
