Inner-outer decomposition of wall shear stress fluctuations in turbulent channels
Theoretical and Applied Mechanics Letters, 2022 Fluctuating wall shear stress in turbulent channel flows is decomposed into small-scale and large-scale components. The large-scale fluctuating wall shear stress is computed as the footprints of the outer turbulent motions, and the small-scale one is ...
