7.1 Physics 231Fig. 7.11 Experimentally measured probability distributions of the velocity differences for theCouette–Taylor experiment at Reynolds number Re = 540,000 for typical values of the distancer are compared with theoretical q-Gaussians: (a) logarithmic plot; (b) linear plot. The rescaleddistances r/η (η is the Kolmogorov length scale) are, from top to bottom, 11.6, 23.1, 46.2, 92.5,208, 399, 830, and 14,400. For better visibility, each distribution in (a) is shifted by −1 unit alongthe y axis, and each distribution in (b) is shifted by −0.1 unit along the y axis (from [433]).
