... Abstract The centrifugal compressor is one of the core components in a supercritical carbon dioxide (SCO2) Brayton cycle, in which the inlet state is near the critical point of CO2 to reduce the compression work. However, the thermodynamic properties of CO2 change dramatically near the critical...
