Figure 19. (a) Inner-normalized turbulence enstrophy profiles plotted as sold lines capped by symbols for clarity. Symbols at start/end of each line correspond to Table 2. (b) Ratio of turbulence enstrophy between boundary layers and pipes of approximately matched spatial resolution. Note the shorthand ω2 = ωiωi is used in (b). Each ratio is multiplied by δ + BL/δ + P to account for the apparent Reynolds number trend when ratios are computed based on x2/δ coordinates (i.e. that associated with ωiωi ∼ x−12 dependence).
