Abstract
This paper deals with a set of time-evolution formulations in algorithms for artificial turbulent field generation based on the Randomized Spectral Method (RSM). We analyze the autocorrelation functions associated with the models considered. The theoretical results are compared to the data from a test computation of turbulence in the cube.
