Numerical simulation of the momentumless turbulent wakes behind sphere

Institute of Computational Technologies SD RAS (Novosibirsk)

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 stresses transformation. The predicted results are compared with experimental data of Aleksenko and Kostomakha( 1987, 1988). One succeeds in obtaining a satisfactory description of the decay of all measured characteristics only by using the mathematical model of Launder et al.(1994).
