Turbulence parameters estimated for the three runs of the numerical simulation. Top panel: energy dissipation rate, ε_tot (arbitrary units), versus the rescaled simulation time, (t − t^*)/t_NL, for the three simulation runs. Bottom panel: magnetic field kurtosis, K, versus the spatial increment Δl, averaged over the field components, shown here for run II at three different times (see legend). For all plots, power-law fits and the relative fitted exponents are indicated (fitting errors ≤0.01).
