title = "Effects of turbulence model on flutter prediction of a transonic fan",
abstract = "Four different turbulence models have been employed to investigate the aeroelastic stability of NASA Rotor 67 and a transonic fan by use of the energy method. Firstly, the amplitude and phase of the first harmonic pressure on blade surface have been analyzed. Then the characteristics of flutter at different working points and nodal diameters have been investigated. Finally, the flutter boundary of the fan has been predicted and compared to the measured one. The simulation results for the steady characteristics by use of k-ε model and k-ω model agree better with the test data than those of the SST model and RNG k-ε model. The aerodynamic damping predicted by use of these models are approximately the same at the peak efficiency point. However, compared to the test data, the aerodynamic damping calculated by use of SST model are more conservative than k-ε model at the near-stall point. Therefore, the k-ε model is more suitable to flutter prediction of transonic fans.",
