Results of calculations of the limiting regime of 
stabilization of the average velocity of a flow and an investigation 
of the behavior of statistical characteristics of turbulence in a 
straight circular tube that rotates about the longitudinal axis based 
on a differential model of transfer of Reynolds stresses are presented. 
It is shown that, in a correct description of transformation of the 
structure of swirling-flow turbulence (Reynolds stresses) with simultaneous 
attainment of a regime of stabilization by the profiles of the axial 
and circumferential components of the average flow velocity, we need 
to allow for the action of the rotation on the spectral expenditure 
of kinetic energy of turbulence.
