In this paper, we describe the structures that produce a spike-type route to rotating stall and
explain the physical mechanism for their formation. The descriptions and explanations are …

The decrease in the performance of centrifugal compressors operating at low Reynolds
numbers (eg, unmanned aerial vehicles at high altitudes or small turbomachines) can reach …

In this two-part paper the phenomenon of part span rotating stall is studied. The objective is
to improve understanding of the physics by which stable and persistent rotating stall occurs …

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 …

The stable flow range of a compressor is dominantly limited by flow instability, known as
surge and stall. In this paper, surge and stall in a turbocharger centrifugal compressor with a …

The development of single-stage high pressure ratio centrifugal compressors for small gas
turbine engines is hindered by compressor flow instabilities with various temporal and …

Centrifugal compressors are widely used in different fields. Their design requires high
performance and a wide operating range, where, at lower mass flow rates, unstable flow …

“Two-regime-surge” is a special instability behavior of compressors, which was investigated
in this paper. When the compressor operates at medium rotor speed, mild surge happens …

The characteristic signal judgment of rotating stall in a centrifugal compressor is necessary
to avoid the compressor becoming instability in operation. This study investigates rotating …

Flow instability conditions, in particular during surge and stall phenomena, have always
influenced the operational reliability of turbocompressors and have attracted significant …
