Simultaneous wall-shear-stress and wide-field Particle Image Velocimetry measurements

The dataset contains simultaneous particle image velocimetry (PIV) and wall-shear-stress sensor measurements in a flat plate turbulent boundary layer a Reynolds number Reτ~4000. The PIV field-ofview covers 8δ (where δ is the boundary layer thickness) along the streamwise direction and captures the entire boundary layer in the wall-normal direction. Simultaneously, wall-shear-stress measurements were taken using a spanwise array of skin-friction sensors (spanning 2 δ). The experiments were performed in the R.J. Mitchell wind tunnel of the University of Southampton.Further details about the dataset can be found in:

本数据集包含平板湍流边界层内同步采集的粒子图像测速（Particle Image Velocimetry, PIV）与壁面切应力传感器测量数据，实验基于雷诺数Reτ≈4000开展。
PIV视场沿流向方向覆盖8δ（δ为边界层厚度），并在壁面法向覆盖整个边界层。
同步采集的壁面切应力数据采用展向排列的表面摩擦传感器阵列获取，阵列展向跨度为2δ。
本实验在南安普敦大学R.J. Mitchell风洞中完成。
