摘要：

Numerical modeling and investigation of the dynamics of a momentumless turbulent wake in a horizontally homogeneous shear flow are performed. The obtained data demonstrate transformation of the turbulized region in awake under the action of a shear flow, and also substantial generation of turbulence energy by averaged motion, which leads to slower turbulence degeneracy at large time values after passage of the body. Some considerations on flow similarity by shear Froude number are presented along with calculation results illustrating this similarity.
