Zusammenfassung:PROBLEM TO BE SOLVED: To improve effective efficiency of a centrifugal compressor by achieving a uniform distribution of fluid velocity at the outlet of a diffuser in an axial diffuser for the centrifugal compressor and a high static pressure recovery ratio Cp. SOLUTION: Minor axes Sa, Sb, Sc... of ellipse or oval shape cross sections at every sections "a", b, c... are directed to a direction passing through a center axis line A of an impeller 11 over a substantially whole area from a diffuser inlet part 32a to the diffuser outlet part 32.
