...Zeyuan Yang; Yadong Wu; Hua Ouyang Rotating instability (RI) and rotating stall (RS) are two types of aerodynamic instability in axial compressors. The former features the side-by-side peaks below the blade passing frequency (BPF) in frequency spectra, and the latter represents one or more stall...

...A. F. Mustaffa; V. Kanjirakkad The stability limit of a tip-stalling axial compressor is sensitive to the magnitude of the near-casing blockage. In transonic compressors, the presence of the passage shock could be a major cause for the blockage. Identification and elimination of this blockage could...

...Jie Tian; Zonghan Sun; Xiaopu Zhang; Hua Ouyang A signal reconstruction algorithm based on the compressed sensing (CS) theory with dual-uniform sampling point (DUSP) distribution is developed and applied to identify the azimuthal mode of axial compressor. A regular failure signal pattern is found...

...R. Emmrich; H. Hönen; R. Niehuis A casing treatment with axial and radial skewed slots ending in a plenum chamber has experimentally been investigated at a highly subsonic axial compressor stage. The aim was to investigate the physical phenomenon of this treatment family that is responsible...

...Ronald Mailach; Konrad Vogeler The stable operating range of axial compressors is limited by the onset of rotating stall and surge. These flow conditions endanger the reliability of operation and definitely have to be avoided in compressors of gas turbines. However, there is still a need to improve...
