Total stress (sum of viscous and Reynolds stress) versus wall-normal distance for Reθ = 5,200 (red open circles) (DeGraaff & Eaton 2000), 7,500 (purple triangles) (Klebanoff 1955), 13,100 (blue stars) (DeGraaff & Eaton 2000), 31,000 (dark yellow lines) (DeGraaff & Eaton 2000), and τ+ = 1 − 0.6y/δ (dashed gray line) (Spalart 1988). An estimate of the uncertainty is shown for the Reθ = 31,000 data.
