Precise judgment of surge point is crucial for compressor performance experiments. Three
types of dynamic measurements (pressure, temperature and acoustic noise) have been …

The impeller is one of the core components of a large-scale centrifugal compressor, and its
performance directly affects the stability and safety of the centrifugal compressor. The non …

Owing to the asymmetric structure of the volute, the internal flow field in a centrifugal
compressor is circumferentially non-uniform. Previous studies have paid little attention to …

In the practical operation of compressors, both surge and deep stall are to be avoided. For a
compressor, the minimum feasible flow is usually obtained in pre-operational tests …

The present paper numerically and experimentally investigates the stall inception
mechanisms in a centrifugal compressor with volute. Current studies about stall inception …

This paper demonstrates that the derivative of Gaussian wavelet with one vanishing moment
can detect the final stable stall cell of the spike-type compressor rotating stall inception. The …

The stall margin and pressure ratio of an axial compressor can both be increased with the
use of circumferential groove casing treatments over the rotor. Performance and stall point …

Experimental investigations of the effect of inlet blade loading on the rotating stall inception
process are carried out on a single-stage low-speed axial compressor. Temporal pressure …

The present work aims to develop a stall warning method that is reliable even when the
compressor encounters inlet distortion. For this purpose, multicorrelation analysis (MCA) is …

This paper presents a new inducer cavitation instability detection method based directly on
quantitative high-speed visualization. The new method uses the grayscale values of pixels …
