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).
