Numerical study of probe parameters on performance of a transonic axial compressor. [PDF]
PLoS ONE, 2021 The paper shows the effect of the probe on the performance of a transonic axial speed compressor. The unobstructed flow case with the experimental data was validated and used as a guide for all subsequent study cases.

Unsteady Deffuser Flow in a Transonic Centrifugal Compressor [PDF]
International Journal of Rotating Machinery, 2002 The paper deals with the clarification of the unsteady, transonic flow phenomena occurring in the vaned diffuser area of a high pressure ratio centrifugal compressor stage. A description of the test rig, the measurement technique applied and a brief description of the steady 3D code used for the theoretical investigations are given.

Transonic Relief in Fans and Compressors [PDF]
Volume 2A: Turbomachinery, 2020 Abstract Every supersonic fan or compressor blade row has a streamtube, the ‘sonic streamtube’, which operates with a blade relative inlet Mach number of one. A key parameter in the design of the ‘sonic streamtube’ is the area ratio between the blade throat area and upstream passage area, Athroat/Ainlet.

Aerodynamic instabilities in transonic centrifugal compressor [PDF]
Mechanics & Industry, 2014 This paper presents the analysis of the instabilities inception in a transonic centrifugal com-pressor for different rotation speeds. The analysis was conducted from experimental results obtained with unsteady pressure sensors implanted in the inducer, vaneless diffuser and vaned diffuser.
