Abstract
Reynolds stress in a rotating system is statistically calculated up to the first order of the scale and rotation parameters by using the two-scale direct-interaction approximation. The results obtained show that the effects of rotation give rise to the anisotropy not only of turbulent energy but also of turbulent viscosity. This fact is incorporated into a Smagorinsky-type subgrid model in the large-eddy simulation of turbulence in a rotating system.
