This is a numerical data repository on 4TU.ResearchData identified through [DOI] thanks to 4TU.ResearchData (https://doi.org/10.4121/64997800-697a-4a94-bb16-f5bb66e8a5ff). The data supports the results presented in the manuscript titled "Validation of the near-wake of a scaled X-Rotor vertical-axis wind turbine predicted by a free-wake vortex model (doi: https://doi.org/10.5194/wes-2025-54)". The data presented here contains 3D flow field data for the X-Rotor types at 36 azimuthal positions as well as 3 pitch offsets, resulting with an overall 108 different cases.
One zip folder, entitled "data_CACTUS_discrete_dynamic_stall_72_azimuth.zip", is provided containing all the corresponding data used in this study. A detailed overview of this data set is presented below. For further details, please check the markdown file 'README.md' to get detailed information on how the study data is structured and how to use it. All of these files require MATLAB R2022a or above or any tools that can read *.mat files to open and use.
