Abstract
A new highly resolved large-eddy simulation is presented for a spatially developing turbulent boundary layer, covering in one single domain the range of Reynolds number Re θ = 180 to 8300. Turbulence statistics are in close agreement with experiments and other simulations. The evolution of the large outer-layer structures is examined using spectra. It is found that the near-wall region is very intermittent, and at high Re θ dominated by strong modulation of the turbulence intensity through the outer structures. The corrugated appearance of the boundary-layer edge is thus directly linked to the turbulence regeneration in the immediate wall vicinity.
