SOWFA simulation setup belonging to the paper: The revised FLORIDyn model: Implementation of heterogeneous flow and the Gaussian wake

SOWFA setup for a nine turbine wind farm in turbulent wind during a wind direction change. This simulation is used as a preliminary indicator on how wakes might behave during changing environmental conditions. The turbines are set up in a 3x3 grid with the initial wind direction coming from 255 deg and then uniformly shifting by -60 deg to 195 deg in a 300 s time frame (from 20600 s to 20900 s). All turbines are 10 MW DTU reference turbines, simulated with an actuator disc. <br> For more details see the relevant files. OpenFOAM 2.4 was used to run the simulation. Content The data set contains the relevant in- and outputs from the simulation and its precursor. This should be sufficient to validate the plots from the related publications and to understand how the simulation was set up. Naturally, you will need to adapt local paths to your installation if you want to rerun the simulation. Note Due to a known bug in SOWFA, the power generated is multiplied twice with the air density. Therefore, to get the actual power generated, divide by 1.225.

SOWFA 仿真设置：针对风向变化过程中湍流风环境下的9台风力涡轮机风电场。本仿真可作为评估环境条件变化时尾流演化规律的初步参考依据。涡轮机以3×3网格排布，初始风向为255°，随后在300秒的时长内（20600秒至20900秒）以均匀速率偏移-60°，最终风向变为195°。所有涡轮机均为10 MW DTU（丹麦技术大学，Technical University of Denmark）参考涡轮机，采用致动盘（actuator disc）模型进行仿真。<br> 更多细节可参阅相关文件。本次仿真采用OpenFOAM 2.4完成运行。数据集内容：本数据集包含本次仿真及其前置仿真的相关输入与输出数据，足以支撑相关出版物中图表的验证工作，并帮助使用者理解该仿真的设置方式。若需重新运行该仿真，需根据本地安装环境调整文件路径。注意事项：由于SOWFA存在一处已知缺陷，生成功率会被空气密度重复相乘两次。因此，若需获取实际生成功率，需将计算结果除以1.225。
