Strong Disturbance

Struts and bifurcations installed in the bypass duct of aeroengines can deteriorate the aerodynamic and acoustic performances of the fan and therefore should be accounted for in the design process. This paper compares two 3-D unsteady RANS simulations of a fan model obtained respectively for an isolated and an installed configuration. In the installed case the strut–bifurcation system creates a strong disturbance of the steady flowfield. This involves a deformation of the rotor wakes during their convection, so that their impingement on the stator generates pressure fluctuations acting as sound sources with strong scattered azimuthal mode orders. The scattering is found by analyzing the acoustic field upstream and downstream of the fan stage. The present results are obtained while the rotor is supersonic (Mtip,rel ≈ 1.24). Since all the blades are identical, no frequency scattering (buzz-saw) does happen in the simulations.
