Representation of different models for the effective Reynolds number for the following values: n_e = 10⁻³ cm⁻³, Re = 100, T = 10⁸ K, v_turb = 300 km s⁻¹, v_th, i = 1000 km s⁻¹, L₀ = 100 kpc, and B_equ = 10⁻⁶ G. In the unmagnetized regime, the solid black line is the Reynolds number that is not modified by the regulation of pressure anisotropies and is given in Eq. (25). Between the limiting magnetic field strengths given in Eqs. (1) and (9), we construct the three different models, Models U, M, and L. The black dotted line corresponds to results obtained from simulations of weakly collisional plasmas presented in St-Onge et al. (2020).
