Summary

Based on the differential second-order model of turbulence unified for arbitrary turbulent Reynolds numbers, an axisymmetric turbulent wake behind a body of revolution in the external turbulence environment is considered. The wind-tunnel experiment, which was carried out, has provided a detailed information on distribution of turbulence characteristics in the near wake. The development of a turbulent wake at arbitrary distances behind a body is modelled numerically. The interaction of the wake turbulence with the external degenerating turbulence has been studied.
