Volume- and time-averaged rms velocity as a function Pr_eff(z_CZ) for all of the current runs (circles). The colours (sizes) of the symbols indicate the Péclet number (relative error) as indicated in the colour bar (legend). The dotted lines show power laws proportional to for reference. The crosses show the scaled results from the non-rotating runs R0P[1,2,6,20] of Karak et al. (2018); see their Table 1.
