Rotating instabilities (RIs) have been observed in axial flow fans and centrifugal
compressors as well as in low-speed and high-speed axial compressors. They are …

The work presented here is an effort to provide a better understanding of the effects of blade
sweep on the flow properties of axial fans. The work is intended to be of particular interest to …

The onset of cavitation causes head and efficiency of a main pump to be reduced
significantly and generates vibration and noise. In order to avoid these phenomena, the inlet …

Als Ursache rotierender Instabilitäten werden instationäre Strömungsvorgänge im
Blattspitzenbereich des Rotors und dessen Auswirkungen auf die gehäusenahen …

In order to the evaluation and identification of the aerodynamic sound source generated
from a door mirror of an automobile, the simple measurement technique using the film-type …

An experimental study was carried out to vary circumferential and radial components of
incoming disturbances for a propeller-type axial fan connected to an anechoically …

The bulk of the noise generated by a system equipped with turbomachines is produced by
the associated turbomachinery. In order to study the interactions of turbulence with the rotor …

The aerodynamic noise source around an automobile door mirror is assessed using a hot-
film sensor. The pressure fluctuation generated by the velocity fluctuation is expressed as …

The physical phenomena of rotary instabilities in industrial compressors and high-pressure
aircraft compressors were investigated, which may be a cause of compressor blade fracture …
