Simulating a Supercritical CO2 Compressor - From Design to Optimization

Supercritical carbon dioxide (sCO2) Brayton cycles are emerging as an alternative to steam Rankine cycles, especially for geothermal and solar applications with relatively low turbine inlet temperatures. High thermal efficiencies and smaller turbomachines make them an attractive alternative to conventional installations, reducing fuel consumption, emissions, and construction costs.

However, designing turbomachinery for sCO2 can be quite challenging due to the extreme heat ratio variations and low compressibility of the gas.

This webinar will demonstrate how to use Cadence's Fidelity CFD platform to perform full computational fluid dynamics (CFD) analysis of a sCO2 centrifugal compressor, from meanline design to optimization.

What you'll learn:

• Generate a 3D geometry of a sCO2 centrifugal compressor from meanline calculations
• Perform CFD analysis of the compressor design using the harmonic method (NLH)
• Run a structural analysis of the compressor model and optimize compressor performances
