Dataset underlying the publication: Development and characterisation of a turbulent boundary layer facility at the Delft University of Technology

This dataset contains the experimental data accompanying a publication on the development and characterisation of a new turbulent boundary layer facility at the Delft University of Technology.We provide data acquired via hot-wire anemometry (HWA), particle image velocimetry (PIV), particle tracking velocimetry (PTV), as well as time-resolved pressure-fluctuation measurements.Measuements of a zero-pressure gradient turbulent boundary layer, interrogated at x=6.8 m, were conducted at four freestream velocities, of nominally 5, 10, 15, and 20 m/s, corresponding to a range in friction Reynolds number of 1400 to 5100.The HWA, PIV, and PTV datasets contain wall-normal profiles of the turbulence statistics, accompanied by the relevant boundary layer characteristics and scaling parameters.Time series are provided for the time-resolved measurements, namely the HWA and the pressure-fluctuation measurements that correspond to the background acoustics and wall-pressure spectrum.

本数据集包含代尔夫特理工大学（Delft University of Technology）一项关于新型湍流边界层实验装置开发与表征的学术出版物配套实验数据。本数据集提供了通过热线风速仪（hot-wire anemometry, HWA）、粒子图像测速法（particle image velocimetry, PIV）、粒子跟踪测速法（particle tracking velocimetry, PTV）获取的测量数据，以及时间分辨压力脉动测量数据。针对在x=6.8m位置探测的零压力梯度湍流边界层，实验设置了四种名义来流速度，分别为5、10、15和20m/s，对应的摩擦雷诺数范围为1400至5100。热线风速仪、粒子图像测速法与粒子跟踪测速法数据集包含湍流统计量的壁法向分布，附带相关边界层特征参数与尺度参数。针对对应背景声学与壁面压力谱的热线风速仪测量及压力脉动测量的时间分辨实验，均提供了时间序列数据。
