摘要

A new technique of stochastic generation of anisotropic turbulent velocity fields is based on Randomized Spectral Method (RSM). The algorithms provide incompressibility of the fields constructed simultaneously with the required statistical properties of turbulence, including the Reynolds-stress tensor and the energy spectrum.
