Abstract (en)
[origin: EP2806170A1] A centrifugal compressor for which ¸-±>0° and 0°<¸<34°, when the angle formed by a diffuser inlet hub-side line (5a) and the radial direction at a point B in the meridian plane is ¸, and the angle formed by a tangent line (3b) and the radial direction at a point A of an impeller hub-side line (3a) nearest the inlet of the diffuser (5) is ±. Thus, skewing of the velocity distribution of a gas within the diffuser of the centrifugal compressor is eliminated.
