Rotation Effects on Turbulence

Part of the International Centre for Mechanical Sciences book series (CISM, volume 329)

Abstract

We consider the general case of a turbulent flow in a rotating coordinate system. Rotation is known to produce anisotropy in a turbulent flow, revealed by an increase of the turbulent lengthscales in the direction parallel to the rotation axis as compared to those in a plane perpendicular to it. This mechanism, which relies on the dimensional analysis presented earlier in this volume by Hopfinger [1], leads to the evolution of turbulence towards a two-dimensional state. Before this process is described in section 2 of the present paper, the effect of rotation on second order correlations (Reynolds stresses tensor) is considered in section 1.
