摘要
The purpose of this paper is to suggest a possible presence of steady hydrodynamical (non-MHD) turbulence in differentially rotating disks. This turbulence is assumed to be described by a second-order closure modeling. It is further assumed that the turbulence is incompressible and locally homogeneous in the horizontal direction, except that a strong differential rotation is present. The results suggest that steady turbulent states might be possible by isotropizing effects of a pressure-strain tenser. The limitations of our approach are discussed briefly.
