Abstract

Direct numerical simulation data are used to visualize coherent structures in turbulent boundary layers at Mach numbers from 0.3 to 7. Different criteria to identify the three-dimensional turbulence structure are selected. We find that using the discriminant of the velocity gradient tensor, the swirling strength and the λ₂ criteria give nearly identical results, with λ₂ identifying more structures very close to the wall.
