This paper is devoted to the study of the properties of astrophysical objects, namely, the study of the processes of development of large-scale turbulence in accretion stellar disks. Such activity is motivated by the need to explain the nature of the mechanisms that lead to the redistribution of angular momentum in the disk and the subsequent accretion of matter to the central gravitating body. Thus, the complete three-dimensional modeling of the processes of instability development in an initially stationary disk allows us to draw conclusions about the efficiency of the redistribution of angular momentum by large-scale vortex structures.
