Numerical Investigation of a Supercritical CO_2 Centrifugal Compressor

摘要

As the next generation reactors are being researched, an alternative power conversion system is required to utilize higher turbine inlet temperature compared to existing nuclear reactors. While various Brayton cycles have been studied, the supercritical carbon dioxide (S-CO_2) Brayton cycle is considered as the most attractive candidate due to its relatively high cycle efficiency in modest temperature range (450～750℃) with compact component size and simple layout .
