- Аннотация: The study is aimed at numerical modeling of turbulent flows, using an artificially generated random field. A multiparametric model of the spectral tensor of covariances of the stream function is proposed, reproducing the most important physical characteristics of a three-dimensional anisotropic turbulent field - incompressibility and quantitative values of Reynolds stresses and turbulence scales, obtained from a preliminary calculation. Adaptation of known methods of generation of a turbulent velocity field to the usage of a given tensor is demonstrated.Перевод статьи из сборника трудов ф-та ВМК "Прикладная математика и информатика"
