摘要：Evolution of coherent vortical structures (CVSs) in shock wave/turbulent boundary-layer interactions (SWBLIs) is a fundamental yet relatively unexplored physical problem. A direct insight into this issue can help understand the SWBLI phenomenon from a more microcosmic perspective and provide new experimental results to the community of high-resolution numerical simulation. Thus, ice-cluster planar laser scattering technique is applied to acquire high spatiotemporal resolution images of the turbulent boundary-layer. Two-dimensional slices (2DS) of CVSs, from which statistical information can be acquired, are extracted by a machine-learning based method. Finally, by comparing features of 2DS-CVSs in the pre-separation zone and the post-reattachment zone, the evolution of CVSs in SWBLI is analyzed. © 2018 Author(s).
