In this paper, a hierarchy of semi-empirical turbulence models of second order is involved for the description of fluid flow in far turbulent wake behind a towed body. Most complex of models includes the differential equations for normal Reynolds stresses transfer. The results of the calculations showing dynamics of a far turbulent wake in linearly stratified medium in comparison with dynamics of momentumless turbulent wake are demonstrated. Numerical modeling of anisotropic decay of turbulence in a far wake behind a towed body is carried out. The characteristics of a turbulent wake are calculated for large moments of decay time. The numerical model of a passive scalar dynamics in turbulent wakes behind bodies of revolution in linearly stratified fluid is constructed. The results of calculations showing behavior of characteristics of a passive scalar both in a momentumless wake, and in a wake behind a towed body are presented.
