Abstract
Provided is a centrifugal compressor, including: a compressor impeller; and a plurality of diffuser blades arranged on an outer side of the compressor impeller in a radial direction so as to be spaced apart from each other in a circumferential direction of the compressor impeller, the diffuser blades each with: a blade angle having a local maximum value, the blade angle being an angle formed between a center line of the diffuser blade and the radial direction; and a thickness having a local maximum on a downstream side of a position at which the blade angle has the local maximum value.

A centrifugal compressor, comprising:
- a compressor impeller;
- and
- a plurality of diffuser blades arranged on an outer side of the compressor impeller in a radial direction so as to be spaced apart from each other in a circumferential direction of the compressor impeller, the plurality of diffuser blades each with:
- a blade angle having a local maximum value, the blade angle being an angle formed between a center line of the diffuser blade and the radial direction;
- and a thickness having a local maximum on a downstream side of a position at which the blade angle has the local maximum value,
- wherein the blade angle monotonically increases as approaching from an upstream end of the diffuser blade toward the position at which the blade angle has the local maximum value, and monotonically decreases as approaching from the position at which the blade angle has the local maximum value toward a downstream end of the diffuser blade.
