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 or solar applications with a relatively low turbine inlet temperature. 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 challenging, as extreme heat ratio variations and low compressibility of the gas directly affect the correlations and empirical equations commonly used in the design process.

Cadence provides the tools to perform and validate the design of a turbocompressor for sCO2 applications efficiently. The design is created using correlations available in the literature and analyzed and validated through steady and harmonic simulations to accurately represent the unsteady flow field. Parametrical optimization and structural analysis are used to assess the final geometry.

In this webinar, learn how to use Cadence’s CFD platform Fidelity to:

  • 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
