Scaling Properties in Rotating Homogeneous Turbulence Available to Purchase

The effects of uniform solid-body rotation on the scaling properties of turbulent flow (considered in a rotating frame) are studied by direct numerical simulation at two rotation rates, with a focus on the statistics of the velocity field including velocity gradients, enstrophy and energy dissipation rate. Especially at the high rotation rate, there is substantial evidence for anisotropy at the small scales, for reduced likelihood of extreme events in both enstrophy and dissipation (whose statistics become some-what alike), and for the failure of classical Kolmogorov scaling in this flow.
