Turbulent disk parameters: planetesimal Reynolds number Re_p (black), dimensionless turbulent intensity I (red), and planetesimal to Kolmogorov scale d/ℓ_Kol (blue) for a MMSN disk model, disk turbulent parameters α = 10^-4 (dashed) and α = 10^-2 (solid) and planetesimal diameter d = 1 km. The blue and black line thus scale up and down with the planetesimal size. The shaded regions are covered by the numerical experiments (see Table 1).
