Spectral analysis of the budget equation in turbulent channel flows at high Reynolds number (2018, background): “…modes on the near-wall layer appears to correspond to the near-wall ‘inactive motions’ that do not carry Reynolds stress, as hypothesised by Townsend (1976), and analysed by many others (Perry et al. 1986; Perry & Marusic 1995; Kunkel & Marusic 2006; Hutchins & Marusic 2007a; Hwang 2015).”
The engine behind (wall) turbulence: perspectives on scale interactions (2017, methodology): “When the small scales are also filtered, as explored by Hwang (2015) using over-damped LES to filter motions smaller than the filter length scale, the minimal box turbulence persists, and the structures can be seen to be consistent with the AEH, a useful link between one of the original scaling…”
