Estimating wall-shear-stress fluctuations given an outer region input (2013, methodology): “These difficulties are compounded in high-Reynolds-number flows where spatial and temporal resolution effects become prohibitive (Hutchins et al. 2009; Smits et al. 2011b).”
A comparison of turbulent pipe, channel and boundary layer flows (2009, background): “Certainly, the peak turbulence intensities are all within the scatter seen in the literature (e.g. Metzger & Klewicki 2001; Hutchins et al. 2009).”
Simulations of Spatially Evolving Turbulent Boundary Layers up to Reθ = 4300 (2010, background): “In particular, for a lower limit of ≥ 250+, the outer peak becomes more dominant than the inner peak (Hutchins et al., 2009).”
Experimental measurement of large-scale three-dimensional structures in a turbulent boundary layer. Part 2. Long structures (2011, background): “Furthermore, the recent work by Hutchins et al. (2009), where the difference in turbulent stresses measured by a hot wire of length l+ = 79 and a hot wire of length l+ = 22 was shown to be negligible in a wall-bounded flow beyond around y+ = 200, (which corresponds to around y/δ ≈ 0.1 in our…”
A predictive inner–outer model for streamwise turbulence statistics in wall-bounded flows (2011, methodology): “…and Princeton have shown that the second outer peak in the u2/U 2τ profile is likely the result of experimental artefacts, mainly due to hot-wire spatial and temporal resolution issues (Hutchins et al. 2009; Bailey et al. 2010); however, the topic remains open at very high Reynolds numbers.”
Evolution of zero-pressure-gradient boundary layers from different tripping conditions (2015, methodology): “This exceeds the minimum timescale for energetic turbulent fluctuations (which is estimated at t+≈ 3, Hutchins et al. 2009), and thus the Nyquist criterion is met and aliasing is unlikely to be an issue.”
Towards Reconciling the Large-Scale Structure of Turbulent Boundary Layers in the Atmosphere and Laboratory (2012, background): “4c also includes boundary-layer profiles at Reτ = 1, 350 (DeGraaff and Eaton 2000) and Reτ = 19, 030 (Hutchins et al. 2009) from laboratory measurements.”
Spatial resolution correction for wall-bounded turbulence measurements (2011, methodology): “In order to be consistent with the traditional approach (that is, as used by Hutchins et al. 2009) we will express our scaling in terms of l, even though l/η may be more physically appropriate. In addition, l is a more practical parameter because for unresolved measurements the behaviour of η is not”
Turbulence measurements using a nanoscale thermal anemometry probe (2010, background): “More recently, Hutchins et al. (2009) provided an empirical correlation to help estimate the filtering effects (at y+ =15) as a function of three parameters: δ+ = δuτ/ν, l + w and lw/δ, where δ is the boundary-layer thickness, and Chin et al. (2009) proposed a correction to the measured…”
High–Reynolds Number Wall Turbulence (2011, methodology): “Data taken from Hutchins et al. (2009).”
Three-dimensional conditional structure of a high-Reynolds-number turbulent boundary layer (2011, methodology): “The measured hot-wire statistics match those previously taken in this same facility in the absence of the spanwise array of hot-film sensors (see Hutchins et al. 2009).”
High Reynolds number effects in wall turbulence (2010, methodology): “This was done to avoid the complication of spatial resolution problems that are prevalent with many turbulence measurements in the near-wall region (Hutchins et al., 2009).”
