Abstract

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.
