Abstract
A method for generating synthetic fields of turbulent velocity fluctuations based on a randomized spectral method (RSM) is proposed. The generated fields have zero divergence, as well as the specified properties of anisotropy and spatial inhomogeneity. The calculation of the canonical problem of a developed turbulent flow in a channel using the generated turbulent fields is in close agreement between the results and the data of direct numerical simulation.
