Overview of Turbomachinery for Super-Critical CO2 Applications
MetadataShow full item record
Cycles involving super critical carbon dioxide (sCO2) have the potential to increase system efficiencies well beyond current industry norms. Research on advanced direct and indirect cycles is ongoing in national labs and major companies. sCO2 machinery tends to have small foot print sizes making for excellent applications in marine, or space limited, environments. As scCO2 turbomachinery gains acceptance in various industries the need to understand the applications, potential, and limits is paramount. Discussed in this tutorial are 1) various direct and indirect cycles 2) various applications, and 3) specific impact to turbomachinery design. Specific applications are described in detail including waste heat recovery, power generation, concentrated solar power, and marine applications. Discussed are transient, thermalmechanical, material, rotordynamic and many other factors affecting the turbomachinery.
