Volume (left) and mass (right) distribution of turbulent diffusion for all runs studied in this paper. We show in red the turbulent diffusion from the AGN-jet of Hydra, in blue the distributions of turbulent diffusion from the sloshing core in Virgo (we plot with different line-styles the distributions at different resolution, as in Sect. 3.2), and in black the turbulent diffusion from cosmological clusters (the different line-styles are for each different object studied in Sect. 3.1, while the shadowed region shows the uncertainty in the overall cluster sample).
