The numerical investigation of momentumless turbulent wakes behind sphere based on semi-empirical turbulence models of second order

The numerical simulation of the momentumless turbulent wakes behind a sphere including the wake under the nonzero turbulent background conditions was carried out with application of modern second order semi-empirical turbulence models. These models based on the differential equations for the set of Reynolds stress transformation. The results are compared with experimental data of Alekseenko and Kostomakha (1987, 1988).
