Figure 2.

Mean (a) total tangential Reynolds stress and (b) streamwise velocity profile for NS550 (– – –), NS550-p (O) and NS550-n (●). Panels (c,d) contain the streamwise (circles and – – –), wall-normal (triangles and – – –) and spanwise (squares and ⋯ ⋯) r.m.s. velocity fluctuations scaled with (c) uτ and (d) u⋆. Symbols are for NS550-p (open) and NS550-n (closed). Lines without symbols are for NS550. For clarity, the profiles for the wall-normal and spanwise r.m.s. velocity fluctuations are shifted vertically by 2.0 and 3.4 wall units.
