Quasi-unsteady Flow Field Computation and Performance Prediction of Contra-Rotating Fan

Quasi-unsteady Flow Field Computation and Performance Prediction of Contra-Rotating Fan

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 rotati...
