Dynamics of a far momentumless turbulent wake in passively stratified media. (English) Zbl 1137.76385

Summary: We numerically model a far momentumless turbulent wake behind a body of revolution in passively stratified media. To describe the flow we use second-order semiempirical models, including models with improved nonlinear representations of pressure-strain terms in equations for transport of the second correlation moments. The numerical analysis of the self-similar decay of flow characteristics is made. The calculated data is in reasonably good agreement with the known results of the analysis of the self-similar decay of turbulent wakes and with experimental data.
