Analyzing a turbulent pipe flow via the one-point structure tensors: Vorticity crawlers and streak shadows

Efforts to identify and visualize near-wall structures typically focus on the region y⁺≳5, where large-scale structures with significant turbulent kinetic energy content reside, such as the high-speed and low-speed streaks associated with sweep and ejection events. While it is true that the level of the turbulent kinetic energy...
