Simulation results for 'Evaluation of Six Subgrid-Scale Models for LES of Wind Farms in Stable and Conventionally-Neutral Atmospheric Stratification' Mina Ghobrial (20646653) Timothy Stallard (13898309) David Schultz (10788456) Pablo Ouro (15572477) Geophysical and environmental fluid flows Environmental engineering not elsewhere classified Atmospheric stability large-eddy simulations (LES) Smagorinsky model subgrid-scale models Wind-farm flow <p dir="ltr">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:<br>1- standard Smagorinsky (Smag.),<br>2- wall-adapting local eddy viscosity (WALE),<br>3- anisotropic minimum-dissipation (AMD),<br>4- one equation turbulent kinetic energy (TKE),<br>5- stability dependent Smagorinsky (SDS), and<br>6- Lagrangian-averaged scale-dependent Smagorinsky (LASDD) models.<br><br>The dataset is organised as follows:<br>1- "SBL" (folder containing results of the stable case), and<br>2- "CNBL" (folder containing results of the conventionally-neutral case).<br><br>Each of the two folders contains the following:<br>a- Matlab scripts that generate the figures, and<br>b- folder titled "results" which contains the simulation results from the different SGS models.<br><br>The subfolder "results" contains a subfolder of the results from each of the SGS models mentioned previously:<br>1- Smag,<br>2- WALE,<br>3- AMD,<br>4- TKE,<br>5- SDS, and<br>6- LASDD.<br><br>The subfolder of each SGS model contains the following subfolders:<br>a- "precursor", and<br>b- "concurrent".<br>The folder titled "precursor" contains files of the horizontal and time averaged vertical profiles of the boundary-layer flow.<br>The folder "concurrent" contains:<br>- files of the horizontal and time averaged vertical profiles of the wind-farm flow,<br>- files providing time history of disc-averaged wind speed, yaw angle, thrust, and power of each turbine,<br>- files providing streamwise distribution of the flow field along the wind farm,<br>- wake profiles, and<br>- terms of the kinetic energy budget over the farm.<br><br>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:<br>- "pre1" (15-m elements)<br>- "pre2" (7.5-m elements)<br>- "pre3" (2-m elements).<br><br>Full details of the numerical setup can be found in:<br>Ghobrial M, Stallard T, Schultz D M, Ouro P (2025) Evaluation of Six Subgrid-Scale Models for LES of</p><p dir="ltr">Wind Farms in Stable and Conventionally-Neutral Atmospheric Stratification.
