When axial compressors operate under high-loading conditions, inherent unsteady flow
phenomena emerge in the tip region as a consequence of the tip leakage flow. These …

Rotating instability (RI) occurs at off-design conditions in compressors, predominantly in
configurations with large tip or hub clearance ratios of s*≥ 3%. RI is the source of the blade …

Rotating instability (RI) as an unsteady phenomenon usually occurs at off-design conditions
in compressors, featuring a broadband hump in the pressure spectra below the blade …

This paper considers the inherent unsteady behavior of the three-dimensional (3D)
separation in the corner region of a subsonic linear compressor cascade equipped of 13 …

Research of the past decades has shown that the operating range of modern fans and
compressors is often limited by aeroelastic phenomena before the onset of pure …

Rotating instability (RI) occurs at off-design conditions in axial compressors, predominantly
in rotor configurations with large tip clearances. Characteristic spectral signatures with side …

Within the present paper a detailed experimental investigation is presented. The influence of
blade loading on the development and interaction of secondary flow structures within an …

Axial compressors in aero engines are prone to suffering a breakdown of orderly flow when
operating at the peak of the pressure rise characteristic. The damaging potential of …

The rotating instability phenomenon is investigated experimentally on a laboratory low-
speed axial fan. Unsteady pressure measurements are performed close to the rotor leading …

To investigate the effects of tip clearance on the rotating instability of a compressor, full-
annulus numerical simulations, with and without clearance, were conducted for a low-speed …
