Abstract: Surge is a crucial problem for achieving a good working range of centrifugal compressor and power cycle safety. Effective and early detection of the surge is essential to avoid its onset. In this paper, experiments measuring ...

Abstract: Stall and surge behaviors deteriorate the compressor performance and stability of the operating range. To avoid the effect of stall and surge behaviors, the characteristics of the pre-stall disturbance have been considered ...

Abstract: Increasing performance requirements and compact structure design promote the generation of axial–radial combined compressors. However, its complex structure and asymmetrical outlet boundary cause difficulty to get an ...

Abstract: The casing-wall static pressure of the centrifugal compressor behaves the double-peak distribution in the circumference at small flow rates (SM) but the single-peak distribution at large flow rates (LM). A previous study ...

Abstract: The present paper numerically and experimentally investigates the stall inception mechanisms in a centrifugal compressor with volute. Current studies about stall inception pay more attention on the axial compressors than ...
