Rotating Turbulent Flow

Abstract. The process of the kinetic energy and kinetic helicity transfer over the spectrum in an incompressible, rapidly rotating turbulent flow is considered. An analogue of the Fjortoft theorem for 3D rapidly rotating turbulence is proposed. It is shown that, similar to 2D turbulence, there are two cascades simultaneously: the inverse cascade of the kinetic energy and the direct cascade of the kinetic helicity, which in the case of 2D turbulence corresponds to the cascade of enstrophy. The proposed scenario is in agreement with our earlier calculations, some recent numerical simulations, and physical experiment on rotating turbulence.

The effect of turbulent mixing in a neutrally buoyant rotating fluid is considered in a region where the mean flow is axisymmetric. The separate actions of molecular and turbulent mixing are distinguished. It is shown that a rotating turbulent flow capable of mixing angular momentum must vary in the axial direction. In particular, it would seem that a secondary circulation is required for a flow to support turbulence over its whole volume. The relative roles of turbulence and secondary circulations in the mixing of angular momentum are discussed.
