Реферат: eng: The numerical analysis of the characteristics of a turbulent flow in momentumless wakes behind a sphere and a prolate body of revolution in a homogeneous and linearly stratified media is performed. The results of the numerical simulation based on modern second- and third-order models of turbulence agree with the known theoretical and experimental data. The proximity between these flows in a number of inherent properties, including the self-similar turbulence decay in the far wake in a homogeneous medium and the interrelation between the second and third invariants of the Reynolds stress tensor are shown. The problem of the interaction between two regions of turbulent perturbations forming on the motion of a sphere and a prolate body of revolution in a homogeneous medium is considered. © 2016, Pleiades Publishing, Ltd.
