Abstract
A numerical model has been constructed and the investigation of the dynamics of a cylindrical localized region of turbulent disturbances in a longitudinal horizontally homogeneous shear flow of a linearly stratified fluid has been carried out. Computational results have shown a considerable generation of turbulence energy at the expense of shear flow gradients. It was also found that the shear flow affects weakly the internal waves generated at the evolution of the turbulent mixing zone.
