Product Description
Fundamental sCO2 cycle analyses. This is an ESPA/Noblis presentation of a study made to look at indirect sCO2 Brayton cycles using a generic heat source from a fundamental thermodynamic prospective. Included are overviews of factors impacting cycle configurations, heat sources and outlines of both indirect and direct Brayton Cycles. Sensitivity Analyses are performed on a number of items that include working fluids, cycle pressure ratios and pressures, turbine inlet temperatures, and turbomachinery efficiencies. The study includes testing various equation of state (EOS) to arrive at reasonable and accurate thermodynamic values for fluids in the critical point region. The results are presented in many summary plots to illustrate the findings to the reader. Additional discussion is available in a final report.
