Early surge detection on a turbocharger used to pressurize a SOFC plant emulator [PDF]
E3S Web of Conferences, 2023 High-speed centrifugal compressors are commonly exploited to pressurize fuel cell-based hybrid energy systems. In such complex plants, because of significant interposed volumes due to fuel cells, dynamic compressor response can induce severe vibrations ...

Experimental Examination of an Axial Compressor as a Basis for an Active Stall Avoidance System
International Journal of Rotating Machinery, 2000 A single-stage subsonic compressor was examined with respect to compressor instabilities. During the inception of rotating stall, the transients of the pressure rise and mass flow were measured as well as their hysteresis.

An Investigation of Stall Inception in Centrifugal Compressor Vaned Diffusers [PDF]
Volume 7: Turbomachinery, Parts A, B, and C, 2011 In compression systems the stable operating range is limited by rotating stall and/or surge. Two distinct types of stall precursors can be observed prior to full scale instability: the development of long-wavelength modal waves or a short-wavelength, three-dimensional flow breakdown (so-called “spike” stall inception).
