| Abstract:The current research on S-CO2 centrifugal compressor of domestic and foreign institutions was introduced from the following two aspects, operating efficiency and condensation effects of sub-scale centrifugal compressor. It was indicated that testing with a sub-scale centrifugal compressor was still the best method to verify the design and theoretical research for compressor in Brayton power cycle system. The distribution of flow field and the effects of the boundary layer inside the centrifugal compressor should be further studied by making use of existing technologies, which could provide theoretical support for the design and optimization of S-CO2 centrifugal compressor. |
| Key words: S-CO2 Brayton power cycle centrifugal compressor |
