Abstract
The numerical model of
momentumless turbulent wake in a horizontally homogeneous shear flow of
linearly stratified medium has been constructed. Based on this model,
the investigation of the wake dynamics has been performed. The obtained data demonstrate
the transformation of the zone of turbulent perturbations and
internal waves generated by the wake under the action of shear flow,
which leads to the deceleration of turbulence decay at large time values
after the body passage.
