000014426 520__ $$2eng$$aThe role of different scales in skin friction generation is investigated in a turbulent channel, at moderately high Reynolds numbers. Three different methods are used: the FIK identity, and two sets of LESs using minimal boxes and selective flow damping respectively. We show that the self-similar coherent motions in the form of Townsend’s attached eddies in the logarithmic layer are the dominant contributors to wall shear stress at sufficiently high Reynolds numbers, whereas the near-wall and outer coherent structures are of limited importance.
