Dimensionless CR transport coefficients in two-fluid turbulence at M_A ≃ 1. The upper and lower rows show M_s ≃ 1 and M_s ≃ 10, respectively. Panels (a), (e), (b), and (f) give D_∥/(cL_box) and D_⊥/(cL_box) as functions of r_L/L_box. Panels (c), (d), (g), and (h) give D_μμ/Ω as a function of μ₀ for r_L/L_box ≃ 8 × 10⁻³ and 8 × 10⁻² (r_L = 10 and 100 cells). Red, blue, and green denote decoupled, intermediate, and strongly coupled runs; shaded regions indicate statistical uncertainties. The blue dotted lines in panels (a), (b), (e), and (f) denote the decoupling scale of the intermediate decoupled run.
