Mass outflow rates of the outflowing gas, mass loading factors, mass-weighted average velocities and mass-weighted average density of the outflowing gas across planes at 2 (left column) and 10 kpc (right column) above the disc plane of the G9 galaxy. The outflow rate quickly drops without CR injection and transport, in the noCR and Advection models. In the Advection-only model, the lack of CR transport prevents the generation of sustained outflows. The outflow rate in the Streaming Boost simulation is very similar to the Advection case at early times and rises to higher values at later times, but the outflow rate is sill weaker than with the other transport models. The isotropic diffusion model and anisotropic diffusion with κ = 3 × 10²⁸ − 1 × 10²⁹ cm² s⁻¹ are more than 10 times more efficient at driving winds compared to the noCR case. The mass average outflow velocity is less affected by the injection of CRs: it is increased at most by a factor of 2 for the highest diffusion coefficient, and is even lower for κ = 3 × 10²⁷ cm² s⁻¹.
