Numerical models of momentumless turbulent wake dynamics in a linearly stratified medium
We examine a comparison of numerical models of momentumless turbulent wake behind a body of revolution in a linearly stratified fluid . One model is based on direct numerical integration of the Navier-Stokes equations in the Oberbeck-Boussinesq approximation (DNS). Another models are constructed using the semi empirical turbulence models including the third order closure approach. The result of calculations is in a good agreement with the known experimental data.
