dc.description.abstract
We study sign changes and scaling laws in the Cartesian components of
the velocity and vorticity of rotating turbulence, in the helicity, and
in the components of vertically averaged fields. Data for the analysis
are provided by high-resolution direct numerical simulations of rotating
turbulence with different forcing functions, with up to 1536 3
grid points, with Reynolds numbers between ≈1100 and ≈5100, and
with moderate Rossby numbers between ≈0.06 and ≈8. When rotation
is negligible, all Cartesian components of the velocity show similar
scaling, in agreement with the expected isotropy of the flow. However,
in the presence of rotation, only the vertical components of the fields
show clear scaling laws, with evidence of possible sign singularity in
the limit of an infinite Reynolds number. Horizontal components of the
velocity are smooth and do not display rapid fluctuations for
arbitrarily small scales. The vertical velocity and vorticity, as well
as the vertically averaged vertical velocity and vorticity, show the
same scaling within error bars, in agreement with theories that predict
that these quantities have the same dynamical equation for very strong
rotation.
