摘要：
We numerically analyse the momentumless turbulent wake evolution in a linearly stratified medium, using two mathematical models. The computational results are compared with experimental data. We consider the model, which satisfactorily describes the process of anisotropy turbulence decay in the wake, taking into account the buoyancy effect in the algebraic model of third-order correlations in the velocity field.
