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), and 6- Lagrangian-averaged scale-dependent Smagorinsky (LASDD) models. The dataset is organised as follows: 1- "SBL" (folder containing results of the stable case), and 2- "CNBL" (folder containing results of the conventionally-neutral case). Each of the two folders contains the following: a- Matlab scripts that generate the figures, and b- 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, and 6- LASDD. The subfolder of each SGS model contains the following subfolders: a- "precursor", and b- "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).
