Abstract

Background rotation may seriously affect the dynamics of fluid flows when the relative importance of the nonlinear acceleration over the Coriolis force becomes small enough. It has a relevant effect on turbulent dispersion and mixing in geophysical and engineering flows, and acts with different mechanisms: the Coriolis force makes the flow strongly anisotropic and reduces the energy dissipation [1, 2]. The background rotation reduces the overall dispersion and particularly in the direction parallel to the rotation axis. At the same time, it leads to the formation of Ekman layers close to the horizontal no-slip boundaries, responsible for an enhancement of the vertical mixing by pumping effects.
