RESUMO:

The present work is focused on the implementation of a computer code in MATLAB® software using the meanline method to predict rotor performance of a centrifugal compressor. Supercritical carbon dioxide, S-CO₂, is considered as working fluid and the Span and Wagner real gas equations of state are used to determine the thermodynamic properties of the fluid. The meanline code predicts rotor parameters such as blade inlet and outlet angles, performance parameters including total temperature, total pressure and efficiency, from the input parameters such as total pressure, total temperature and rotational speed. The code was validated by comparing the numerical results with experimental data available in the open. The optimization procedure is applied to the code using the NSGA-II, whose objective function is the maximization of isentropic efficiency obtained by the variation of fourteen input parameters.
