LES of Wind Turbine in Yaw with ABL Inflows

Wind turbine outputs from Large Eddy Simulations of a single wind turbine operating under three different atmospheric inflow conditions: conventional neutral boundary layer (inflow velocity approximately 8.5m/s, 5.5% turbulence intensity); stable boundary layer (inflow velocity approximately 8.6m/s, 3.3% turbulence intensity); convective boundary layer (inflow velocity approximately 8.4m/s,14.6% turbulence intensity). Total simulation length of 2 hours, data from the last 1 hour. Grid resolution of 16 cells/radius, and the turbine is modelled with an actuator disc method, using the EllipSys3D-Flex5 coupling to compute turbine power and loads. Folders are different atmospheric inflow, turbine yaw and modelling combinations: e.g. 'CNBL_AD00': conventionally neutral boundary layer inflow, actuator disc turbine modelling, 0 degrees yaw. Files uploaded are in .nc format containing the three velocity components, split into mean and fluctuating parts, over three planes. The planes are 3 diameters wide and 2.5 diameters tall, normal to the streamwise direction. Position 1 (files named pos01) is 2 diameters infront of turbine; position 2 is 2 diameters behind the turbine; position 3 is 6 diameters behind the turbine. The files also contain the mean velocity and mean turbulence intensity at hub height, rotor radius, and x,y,z coordinates of the planes relative to the turbine location. READme file contains further details including variable definitions. More data, such as 10 and 30 degrees yaw for all cases, planes at every 1D downstream, and some turbine outputs, are available for all simulations.

本数据集包含单台风力机在三种不同大气来流条件下的大涡模拟（Large Eddy Simulations）风机出力数据：常规中性边界层（来流风速约8.5m/s，湍流强度5.5%）、稳定边界层（来流风速约8.6m/s，湍流强度3.3%）以及对流边界层（来流风速约8.4m/s，湍流强度14.6%）。模拟总时长为2小时，取最后1小时的数据作为有效数据。网格分辨率为16个网格/转子半径，风机采用致动盘法（actuator disc method）建模，通过EllipSys3D-Flex5耦合计算风机功率与载荷。文件夹按不同大气来流、风机偏航角（yaw）与建模方式组合命名，例如'CNBL_AD00'代表常规中性边界层来流、致动盘风机建模、偏航角0度的工况。所上传的文件均采用.nc格式，包含三个速度分量，分为平均场与脉动场，覆盖三个垂直于来流方向的平面。三个平面的宽度为3倍风机直径，高度为2.5倍风机直径；位置1（文件命名为pos01）位于风机前方2倍直径处，位置2位于风机后方2倍直径处，位置3位于风机后方6倍直径处。文件同时包含轮毂高度处的平均风速与平均湍流强度、转子半径，以及各平面相对于风机位置的x、y、z坐标。数据集附带的README文件包含更多细节，包括变量定义说明。本系列模拟还提供更多数据，例如所有工况下10度与30度偏航角的结果、每1倍下游直径间距的平面数据，以及部分风机出力数据。若需获取更多细节，请联系邮箱[e-mail]。
