Inlet Flow Distortions in Centrifugal Fans [PDF]
1984 Joint Power Generation Conference: GT Papers, 1984 Recent measurements of the performance of a centrifugal fan subjected to inlet flow distortion are presented. Results of axial and multilobed distortion modes are discussed in the context of a previously published study to provide a more comprehensive evaluation of related fan performance degradation.

Control of Inflow Distortion in a Scarf Inlet [PDF]
8th AIAA/CEAS Aeroacoustics Conference & Exhibit, 2002 The scarf inlet has the potential to reduce aircraft inlet noise radiation to the ground by reflecting it into the space above the engine. Without forward motion of the engine, the non-symmetry of the inlet causes inflow distortion which generates noise that is greater than the noise reduction of the scarf.

Experimental and Numerical Analysis of a Compressor Stage under Flow Distortion
International Journal of Turbomachinery, Propulsion and Power, 2021 On many occasions, fan or compressor stages have to face azimuthal flow distortion at inlet, which affects their performance and stability. These flow distortions can be caused by external events or by some particular geometrical features.
