• Direct numerical simulation of the turbulent boundary layer over a cube-roughened wall (2010, background): “These results suggest that the wall similarity and its necessary conditions may not be universal for the given flow types (Snyder & Castro 2002; Bakken & Krogstad 2005; Flack et al. 2007), and additionally, it plausibly seems to be related to other factors, e.g. dimensions of roughness and…”
• The rough-wall turbulent boundary layer from the hydraulically smooth to the fully rough regime (2006, background): “Snyder & Castro (2002) also noted the difficulties in defining the onset of the fully rough regime for disparate roughness types.”
• Rough-wall boundary layers: mean flow universality (2007, background): “…of the roughness and are related via U+ = A + 1 κ ln(Re∗) ≡ A + 1 κ ln(h+) + 1 κ ln ( y0 h ) , (1.3) where Re∗ is the roughness Reynolds number, y0uτ/ν, which must usually exceed at least O(1) for fully rough conditions to exist – i.e. for viscous effects to be negligible (Snyder & Castro 2002).”

• Aerodynamic Parameters of Regular Arrays of Rectangular Blocks with Various Geometries (2009, background): “According to Snyder and Castro (2002) , a boundary layer over a fully rough surface, where the effect of viscosity is negligible, is observed if the roughness Reynolds number Re ∗ based on the roughness length and friction velocity exceeds O (1).”
