TL;DR: A modified method for predicting the total drag of a spatially developing turbulent boundary layer (TBL), such as that on the hull of a ship, is presented, numerically integrates the skin friction over the length of the boundary layer, assuming an analytical form for the mean velocity profile of the TBL.

TL;DR: In this article, different spectral filters (temporal, spatial, or both) and empirical mode decomposition (EMD) are evaluated and compared for scale decomposition in wall-bounded turbulent flows.

TL;DR: In this paper, the interactions of large-scale free-stream turbulence with turbulent boundary layers were studied. But the authors focused on the interaction of large scale free-flow turbulence with boundary layers.

TL;DR: In this paper, a correlation analysis on a per-scale basis between the velocity and reference skin friction signals is performed to reveal which velocity-based turbulent motions are stochastically coherent with turbulent skin friction.

TL;DR: In this paper, the influence of large scale organisation of free-stream turbulence on a turbulent boundary layer is investigated experimentally in a wind tunnel through hot-wire measurements, and it is shown that while qualitatively the spectra at various wall normal positions in the boundary layer look similar, there are quantifiable differences at the large wavelengths all the way to the wall.
