The effect of laminar and turbulent boundary layers on the localization of pulsed discharge glow in gas in rest and in flow in a gasdynamic channel is studied. It is found that the glow of a discharge localized into the separation zone on a glass surface is of the form of regular structures capturing the structure of turbulent inhomogeneities in the boundary layer. The flow visualization was performed using a pulsed space discharge with UV preionization realized in a working chamber of rectangular section.

冲击波后通道玻璃表面湍流边界层的特征

研究了层流和湍流边界层对静止气体和气体动力通道中流动的脉冲放电辉光局部化的影响。发现位于玻璃表面分离区的放电辉光具有规则结构的形式，捕获边界层中湍流不均匀性的结构。流动可视化是使用脉冲空间放电进行的，在矩形截面的工作室中实现了 UV 预电离。
