Supercritical CO2 Cycle and Turbomachinery Design and Analysis Course

Interest in supercritical carbon dioxide (sCO₂) in closed-loop power cycles and high-efficiency cooling has significantly increased in recent years. These applications benefit from the unique properties of CO₂ near the critical point, but they also pose unique challenges for turbomachinery design.

This course seeks to educate the engineer on the basics of sCO₂ turbomachinery design. We will identify the basic issues, tradeoffs, and limitations involved in laying out cycles and their sizing requirements. The special challenges related to turbomachinery design and analysis will be covered and the most suitable applications to sCO₂ cycles will be discussed. Basic aerodynamic and structural design issues unique to sCO₂ will also be emphasized. This course assumes some basic knowledge of thermodynamics, structural mechanics, and fluid mechanics concepts. Prior know-how of conventional turbomachinery design is beneficial but not required.
