Mean Flow Statistics from Large-Eddy Simulations of Offshore Hybrid Wind-Solar Farms

<p>
The dataset contains a suite of Large-Eddy Simulation (LES) results of neutral boundary layers with various combinations of heated surface patterns and wind turbine arrangements. The simulation are driven by a fixed pressure gradient, and the surface temperature pattern is imposed.

All simulations were run until a true statistically steady state was reached, after which turbulence statistics were collected over a period of approximately 24 hours. The repository includes 3D fields of first- and second order statistics of flow variables, i.e. velocity components, pressure and temperature. The dataset is generated with the SP-Wind code, an in-house DNS/LES code developed at KU Leuven. For details of the code structure and simulation set-up we refer to Bon et al. (2025).

The repository contains all simulations that are listed in Table 1 of the related publication. Each simulation has a separate folder, containing hdf5 files of the time-averaged flow statistics from the main domain (fields_main.h5) as well as the precursor domain (fields_precursor). Note that the latter domain does not contain any surface heterogeneity. Fore more information, we refer to the README.txt file located in the dataset and to the related publication. Some postprocessing scripts that can be used to read and plot the data is also present.
