High-TI Synthetic Inflow Dataset for the G1 Wind Farm Control Benchmark

This repository provides High turbulence intensity (High-TI) synthetic atmospheric boundary layer inflow field generated through large-eddy simulations (LES) and used in numerical studies of wind-farm control strategies. The inflow field was generated using the Simulator fOr Wind Farm Applications (SOWFA) framework. The numerical setup explicitly reproduces the spires and roughness elements used in the wind-tunnel facility, allowing the numerical simulations to replicate the atmospheric boundary layer conditions generated in the wind-tunnel experiments. The simulation reproduces the wind-tunnel inflow used in the experimental campaign of the three-turbine G1 wind-farm benchmark. Velocity fields were sampled along a vertical plane located 19.1 m downstream of the inlet, corresponding to 10 m upstream of the turntable center in the wind-tunnel setup. This location is therefore very close to the experimental inflow measurement plane. For each time step: the three velocity components (u, v, w) are provided values are sampled at the LES mesh nodes The mesh node coordinates are provided in a separate file. Temporal resolution and duration are: Case Duration Time step High-TI ABL ~40 s 1 ms The inflow fields can be scaled using the same procedure applied to the experimental inflow measurements, as described in the associated dataset paper. This inflow has been used to numerically assess how representative the wakes of G1 wind turbines are of full-scale wakes.本数据集仓库提供通过大涡模拟（large-eddy simulations, LES）生成的高湍流强度（High-TI）合成大气边界层入流场，该数据集可用于风电场控制策略的数值研究。 该入流场基于风电场应用模拟器（Simulator fOr Wind Farm Applications, SOWFA）框架生成。本次数值建模过程明确复现了风洞实验装置中的尖塔与粗糙元，使数值模拟能够精准复现风洞实验中生成的大气边界层条件。 本次模拟复现了三涡轮G1风电场基准试验中采用的风洞入流。 速度场沿入口下游19.1 m处的垂直平面进行采样，该位置对应风洞装置中转台中心上游10 m处，因此非常接近实验入流测量平面。 针对每个时间步，均提供三个速度分量（u、v、w）的数据，采样点取自大涡模拟网格节点，网格节点坐标将单独存储于独立文件中。 时间分辨率与总时长如下： | 工况 | 总时长 | 时间步长 | |------|--------|----------| | High-TI ABL | ~40 s | 1 ms | 该入流场可采用与实验入流测量相同的缩放流程进行归一化，具体细节详见关联数据集论文。 本入流场已被用于数值评估G1风电场涡轮尾流对全尺寸尾流的代表性。
