A direct numerical simulation study on the mean velocity characteristics in turbulent pipe flow (2008, background): “At ReD =5300 there exists a short region of 40 < (1 − r)+ < 80 with a local minimum value of 2.76 in du+z /d ln(1 − r)+. Figure 14 also shows that for the case of a+ = − 8 as suggested by Wosnik et al. (2000), the narrow constant du+z /d [ln(1 − r)+ + a+] region merely shifts closer to the wall.”
Scaling of the streamwise velocity component in turbulent pipe flow (2004, unknown): “12R, from the results of figures 17 and 18, it is clear that, although Su and Fu are relatively constant, their variation is such that this definition is unlikely to be as rigorous as that provided by any form of overlap analysis (Zagarola & Smits 1998; Wosnik et al. 2000; McKeon et al. 2004).”
Turbulent fluctuations above the buffer layer of wall-bounded flows (2008, background): “Note that, while all these results are strongly supportive of the attached-eddy scenario of Townsend (1976) , most of them are independent of any specific model for the geometry of the eddies.”
Scaling of the energy spectra of turbulent channels (2003, background): “The data in figure 5(d) collapse reasonably well to (3.4) in the outer layer, even though Wosnik, Castillo & George (2000) have shown that other flow features differ in that region between boundary layers and parallel flows.”
A new friction factor relationship for fully developed pipe flow (2005, background): “At about the same time, Wosnik, Castillo & George (2000) suggested that an offset was required in pipe and channel flows to account for the mesolayer, a region in which the overlap argument in the mean velocity holds, but the separation between the energy and dissipation scales is not large enough”
High–Reynolds Number Wall Turbulence (2011, methodology): “…analytical side, a number of influential scaling arguments have been advanced, principally by Barenblatt et al. (1997), George & Castillo (1997), Wosnik et al. (2000), Monkewitz et al. (2007), Nagib et al. (2007), and Jones et al. (2008), with regard to the log-law/power-law debate (Marusic et…”
Properties of the mean momentum balance in turbulent boundary layer, pipe and channel flows (2005, background): “…data, Perry, Hafez & Chong (2001), while the comparison of the gradient functions, y+(dU+/dy+) and (y+/U+)(dU+/dy+), for respectively determining logarithmic or power law forms, presents stringent demands on the data quality relative to the subtleties of the issues at hand, Wosnik et al. (2000).”
