Time-averaged kinetic spectra at saturation of some representative simulations of Tables 1–3. We notice how the results on large scales (small k) are very similar for all the models, excluding H_0cW1 (dash-dotted green line), which has a forcing with k_f = 2. The spectrum with lowest power is H_0s (dashed green line), which has Δt = 1. Models marked with other colors explore variation of Ω and EoS. In all these models the magnetic field decays rapidly and kinetic spectra coincide with the corresponding HD runs of Fig. 2.
