Direct numerical simulation of the turbulent boundary layer over a cube-roughened wall (2010, background): “In a flow visualization study of TBLs over a smooth wall, Kline et al. (1967) found that low-speed streaks are present in the near-wall region and that the mean spanwise 400 J. H. Lee, H. J. Sung and P.-Å. Krogstad spacing between the streaks is ∼100 viscous wall units.”
Direct numerical simulation of hypersonic turbulent boundary layers. Part 3. Effect of Mach number (2011, result): “As far as the spanwise spacing of near-wall streaks is concerned, figure 20 shows that an increasing free-stream Mach number slightly decreases the streak spacing, and the spanwise spacing is approximately 100 viscous wall units, similar to the values reported by Runstadler, Kline & Reynolds (1963),”
Spatial resolution correction for wall-bounded turbulence measurements (2011, result): “This viscous scaling is consistent with the findings of Kline et al. (1967) and many others that the near-wall streaks scale with wall units over a large Reynolds number range, with a spacing of nominally 100ν/uτ .”
A predictive inner–outer model for streamwise turbulence statistics in wall-bounded flows (2011, background): “Since the early observations of the recurrent near-wall streaks by Kline et al. (1967), which are believed to play a key role in turbulence regeneration, numerous studies have focused on the small-scale near-wall features.”
Structure of the airflow above surface waves (2016, background): “…nonetheless notice that high-vorticity layers (probably due to ejections and sweeps, see above) predominantly originate from the surface just past wave crests, which is coherent with the assumption that they occur more frequently in adverse pressure conditions (Kline et al. 1967; Kovasznay 1970).”
Colour of turbulence (2016, background): “This wavelength pair is associated with the near-wall system of quasi-streamwise streaks and counter-rotating vortices which is responsible for large production of turbulent kinetic energy (Kline et al. 1967; Smith & Metzler 1983).”
Towards Reconciling the Large-Scale Structure of Turbulent Boundary Layers in the Atmosphere and Laboratory (2012, background): “Laboratory observations over a range of Reynolds numbers (Kline et al. 1967; Smith and Metzler 1983; Robinson 1991) have confirmed that the spanwise spacing and length of the near-wall streaks scale with the viscous length scale (average spanwise spacing of 100ν/Uτ and streamwise length in the…”
Near-wall streak modification by spanwise oscillatory wall motion and drag-reduction mechanisms (2012, background): “…a canonical boundary layer is of the order of 103 wall units (Kreplin & Eckelmann 1979), and that the streaks are separated by a † Email address for correspondence: e.touber@imperial.ac.uk distance of the order of 102 wall units (Schraub & Kline 1965; Kline et al. 1967; Kim, Kline & Reynolds 1971).”
Coherent structures in wall-bounded turbulence (2017, background): “The streak is appr ximately straight and steady most of the time, and occasion lly meanders and breaks down into a burst of vorticity and wall-normal velocity hat rec lls t e observations of tracers in early xperiments with boundary layers (Kline et al. 1967).”
The lift-up effect : The linear mechanism behind transition and turbulence in shear flows (2014, background): “the most probable spanwise wavelength of near-wall streaks [68,69].”
