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.
