This dataset provides the baseline geometry and reference data of a compressor airfoil investigated within the EU-Horizon Sci-Fi-Turbo project. It includes experimental and numerical results used to assess the predictive accuracy of scale-resolving simulation approaches and to serve as a benchmark for single- and multi-fidelity optimization methods in turbomachinery. Further details on the dataset structure and usage are provided in the accompanying README.md and pp_lrn_ogv.ipynp. Reference publication listed in the related work tab.
