Data underlying the PhD thesis: Receptivity of Swept Wing Boundary Layers to Surface Roughness

3 Sets of data were acquired from different experimental measurements dedicated to characterising the boundary layer of a swept wing dominated by crossflow instabilities. The Planar_PIV folder contains data acquired with planar PIV and describes the boundary layer spanwise and wall-normal velocity components at various chord locations. The HWA folder contains hot wire anemometry acquisition measuring the velocity fields in the spanwise and wall-normal direction. These fields are acquired in the vicinity of a roughness element. The Planar_PIV_control folder contains planar PIV fields describing the boundary layer spanwise and wall-normal velocity components at various chord locations in the presence of passive flow control on the wing. All folders are accompanied by thermal images acquired through infrared thermography, which provide the global boundary layer behaviour (i.e. laminar or turbulent state). More info on data acquisition and processing can be found in the corresponding PhD Thesis.本数据集包含3组源自不同实验测量的实测数据，用于表征以横流失稳为主导的后掠机翼边界层特性。Planar_PIV文件夹内存储了采用平面粒子图像测速（Planar Particle Image Velocimetry，PIV）采集的数据，描述了不同弦长位置处边界层的展向与壁法向速度分量。HWA文件夹存储了热线风速仪（Hot Wire Anemometry，HWA）采集的速度场数据，其测量对象为展向与壁法向方向的速度场，且采集区域位于粗糙元附近。Planar_PIV_control文件夹存储了平面PIV速度场数据，描述了机翼加装被动流动控制装置时，不同弦长位置处边界层的展向与壁法向速度分量。所有文件夹均配套有红外热成像（Infrared Thermography）采集的热图像，可用于获取边界层的整体流动行为，即层流或湍流状态。有关数据采集与处理的更多细节，可参阅对应的博士学位论文。
