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 …

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 …

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 …

This paper presents a design strategy for very low flow coefficient multistage compressors
operating with supercritical CO2 for carbon capture and sequestration (CCS) and enhanced …

This paper describes in detailed flow field in a centrifugal compressor with a vaned diffuser
at off design point. Especially, we conducted both the experimental and numerical analysis …

Experiments preformed in the JHU refractive index matched facility examine flow
phenomena developing in the rotor passage of an axial compressor at the onset of stall …

Modern compressor design targets require high performance and a wide operating range in
order to reduce the environmental impact. To understand the fluid dynamics mechanisms …

Flow instability, known as surge and stall, limits the stable operating range of compressors.
In this paper, a panoramic map of instability evolution across all typical operations is …

High-speed centrifugal compressor requirements include a wide operating range between
choking and stall especially for turbocharging applications. The prediction of the stability …

A sufficient understanding of the stall behavior is crucial to improve the stability of a
compressor. The stall development process and its sensitive locations in a centrifugal …
