Wall-bounded turbulent flows at high Reynolds numbers have become an increasingly active area of research in recent years. Many challenges remain in theory, scaling, physical understanding, experimental techniques, and numerical simulations. In this paper we distill the salient advances of recent origin, particularly those that challenge textbook orthodoxy. Some of the outstanding questions, such as the extent of the logarithmic overlap layer, the universality or otherwise of the principal model parameters such as the von Karman “constant,” the parametrization of roughness effects, and the scaling of mean flow and Reynolds stresses, are highlighted. Research avenues that may provide answers to these questions, notably the improvement of measuring techniques and the construction of new facilities, are identified. We also highlight aspects where differences of opinion persist, with the expectation that this discussion might mark the beginning of their resolution.

Logarithmic scaling of turbulence in smooth- and rough-wall pipe flow (2013, background): “…thickness, which in a pipe is its radius R. Classical scaling works very well for the mean velocity profile in fully developed smooth pipe flow, as comprehensively demonstrated by Zagarola & Smits (1998) and McKeon et al. (2004), among others (Marusic et al. 2010c; Smits, McKeon & Marusic 2011a).”
Spectral analysis of the budget equation in turbulent channel flows at high Reynolds number (2018, methodology): “…EΨ (k, y) dk. (3.14c) Selecting a cutoff wavenumber is somewhat arbitrary and controversial in the context of defining the large scales (Hutchins et al. 2009; Monty et al. 2009; Marusic et al. 2010c; Ganapathisubramani et al. 2012; Wu, Baltzer & Adrian 2012; Chin et al. 2014; Ahn, Lee & Sung 2017).”
Estimating wall-shear-stress fluctuations given an outer region input (2013, methodology): “…understanding of Reynolds number effects in the turbulent boundary layer, which are now well established to be closely related to the strengthening of the large scales with Re (Townsend 1976; Adrian et al. 2000; Metzger & Klewicki 2001; del Álamo et al. 2004; Marusic et al. 2010a, and others).”
Towards Reconciling the Large-Scale Structure of Turbulent Boundary Layers in the Atmosphere and Laboratory (2012, background): “A thorough reading on coherent structures in laboratory flows can be found in the reviews of Robinson (1991), Panton (2001), Klewicki (2010), Marusic et al. (2010b) and Smits et al. (2011).”
Turbulent boundary layers at moderate Reynolds numbers: inflow length and tripping effects (2012, background): “However, the question regarding the quantification of a sufficient development length and the appropriate tripping 8 P. Schlatter and R. Örlü method still remains open today as emphasized in the recent review article by Marusic et al. (2010).”
High–Reynolds Number Wall Turbulence (2011, methodology): “The inner-outer interaction was considered by Hutchins et al. (2009) and Marusic et al. (2010a), who decomposed the velocity signatures across a boundary layer into small-scale (λx < δ) and large-scale (λx > δ) contributions using a simple cutoff spectral filter.”
History effects and near equilibrium in adverse-pressure-gradient turbulent boundary layers (2017, background): “…by Townsend (1956) this condition is only satisfied by the sink flow, although it is possible to define a less restrictive near-equilibrium condition when the mean velocity defect U∞ − U is self-similar in the outer region, which in any case dominates at high Reynolds numbers (Marusic et al. 2010).”
On the logarithmic region in wall turbulence (2013, background): “The past decade or so has also seen vigorous discussion challenging the universality of κ , and this topic has been extensively reviewed by Klewicki (2010), Marusic et al. (2010), Smits, McKeon & Marusic (2011) and Jiménez (2012).”
Turbulent boundary layers around wing sections up to Rec=1,000,000 (2018, background): “(2001)), certain pressure-gradient conditions exhibit selfsimilarity in their outer region at high Reynolds numbers (Marusic et al., 2010).”
A critical-layer framework for turbulent pipe flow (2010, background): “A region in the flow where an apparent amplitude modulation of the small scales occurs has been identified and explored by Blackwelder & Kovasznay (1972), Bandyopadhyay & Hussain (1984), Hutchins & Marusic (2007b), Mathis et al. (2009) and Guala et al.”
Velocity statistics in turbulent channel flow up to $Re_{\tau }=4000$ (2014, result): “The resulting distributions, not shown, have no significant plateau, which leads us to believe that the logarithmic law is more robust than the power law, in agreement with most current literature on the subject (Marusic et al. 2010).”
Eulerian and Lagrangian views of a turbulent boundary layer flow using time-resolved tomographic PIV (2011, background): “A review on Taylor’s hypothesis and problems occurring when using it especially in TBL’s due to observed bi-modal effects in the spectrum has been given by Moin (2009). He reports on recent investigations on adapting the dependency of the local convection velocity from the distance to the wall and t”
