Simulation results for 'Evaluation of Six Subgrid-Scale Models for LES of Wind Farms in Stable and Conventionally-Neutral Atmospheric Stratification'

This dataset presents the LES results and Matlab scripts necessary to generate vertical profiles of various flow variables (e.g., wind speed and direction) for stable and conventionally-neutral boundary-layer flows. Additionally, results from LES of wind-farm flow under these two stability conditions are provided. The results are generated using six different SGS models, namely:1- standard Smagorinsky (Smag.),2- wall-adapting local eddy viscosity (WALE),3- anisotropic minimum-dissipation (AMD),4- one equation turbulent kinetic energy (TKE),5- stability dependent Smagorinsky (SDS), and6- Lagrangian-averaged scale-dependent Smagorinsky (LASDD) models.The dataset is organised as follows:1- "SBL" (folder containing results of the stable case), and2- "CNBL" (folder containing results of the conventionally-neutral case).Each of the two folders contains the following:a- Matlab scripts that generate the figures, andb- folder titled "results" which contains the simulation results from the different SGS models.The subfolder "results" contains a subfolder of the results from each of the SGS models mentioned previously:1- Smag,2- WALE,3- AMD,4- TKE,5- SDS, and6- LASDD.The subfolder of each SGS model contains the following subfolders:a- "precursor", andb- "concurrent".The folder titled "precursor" contains files of the horizontal and time averaged vertical profiles of the boundary-layer flow.The folder "concurrent" contains:- files of the horizontal and time averaged vertical profiles of the wind-farm flow,- files providing time history of disc-averaged wind speed, yaw angle, thrust, and power of each turbine,- files providing streamwise distribution of the flow field along the wind farm,- wake profiles, and- terms of the kinetic energy budget over the farm.All simulations are conducted using an isotropic grid of 7.5-m elements. However, the SBL precursor flow is run using two additional grids of 15 m and 2 m. Therefore, in the "SBL" results, the folder "results" contains six subfolders for each of the SGS models, the "precursor" subfolder in each of them is classified into three subfolders:- "pre1" (15-m elements)- "pre2" (7.5-m elements)- "pre3" (2-m elements).Full details of the numerical setup can be found in:Ghobrial M, Stallard T, Schultz D M, Ouro P (2025) Evaluation of Six Subgrid-Scale Models for LES ofWind Farms in Stable and Conventionally-Neutral Atmospheric Stratification.
