Preliminary computational study of centrifugal compressor inlet flow instabilities with radial inlet guide vanes

The paper presents the research of flow instabilities in inlet part a centrifugal compressor channel equipped with radial guide vanes. A simplified model is created and for that, dimensional analysis carried out. Methods computational fluid dynamics (CFO) are employed parametric study, which gives basic information about influence dimensionless parameters to field. Reconstruction comprehensive measurement data from an experimental single stage mounted several stages variable capacity done purpose comparison model. Further analyses will be published later.
