RESUMO

A numerical model of dynamics of turbulent wake with small excess momentum has been created on the basis of the three-dimensional parabolized system of averaged equations for motion, continuity, incompressibility, energy of turbulence and the rate of dissipation transfer. The calculation results show that as in the case of homogeneous fluid the wake's excess momentum of order of ±5−10 % from the total momentum in drag wake has weak influence on the decay of the turbulent energy and more significant influence on the axis value of the defect of the longitudinal velocity component. The turbulent wakes with small total excess momentum generate internal waves which are differed insignificant from the waves generated by momentumless wakes .
