Discussion of numerical flow field prediction with two rotor-stator interface models is presented in the paper. The mixing plane and harmonic models are applied to contra rotating fan. Both models confirmed good performance and high power density leading to compact configuration of the contra rotating fan compared to centrifugal fan. The harmonic model provides realistic wake and potential effect propagation through the rotor-rotor interface. In addition, it provides user with static pressure frequency and amplitude inputs for aerodynamic noise assessment.
