Abstract
A numerical analysis of the evolution of momentumless turbulent wakes in a linearly stratified fluid has been carried out by using a hierarchy of semi -empirical turbulence models of second order. The computational results are compared with known experimental data. Simplified models of a far turbulen t wake and the internal waves generated by its collapse are constructed.
