摘要：
Abstract: This work studies a stochastic method for the generation of artificial three-dimensional, divergence-free, homogeneous, and isotropic velocity fields. The technique is based on the randomized spectral method. The statistical and spectral properties of turbulent fields constructed by this generator are analyzed. A validation LES-based computation which uses the obtained turbulent fields as initial conditions, demonstrates good agreement of the results with the experimental data. © 2020, Pleiades Publishing, Ltd.
