Notes. Angular velocity Ω and shear S are in multiples of the angular velocity of our Galaxy in the solar neighborhood, Ω0 = 25 km s−1 kpc−1, with q = −SΩ. The Coriolis number, Co, is defined in Eq. (9), and Re by Eq. (10). Δt is the time span of the statistically steady state over which the data have been evaluated, in multiples of the run-specific turnover time, . In each case this corresponds to Δt = 300 Myr. The time-averaged total thermal, Eth , and kinetic, Ekin, energy are expressed relative to the typical energy injected per SN. The anisotropies of the velocity field AH and AV are defined in Eqs. (13) and (14), respectively. We also list the total number of SNe injected over Δt.
