Discussion

Numerical simulations evaluate CO2 compressor dynamics near condensation, highlighting modeling gaps in fluid dynamics.

Maximum deviations of 4.1% were observed in outlet pressures and temperatures for the CO2 compressor.
The study utilized Peng-Robinson and Redlich-Kwong equations for accurate modeling of real gas behavior.
Thermodynamic analysis indicated localized condensation effects were not captured by single-phase simulations.
Two-phase CFD methodologies are crucial for improved predictions of phase-transition behavior in CO2 systems.

Fateeva et al. (2025) studied this question.
