| Abstract: | The link is established between turbulent unsteady flows, with imposed periodicity, and cyclostationary processes, often met in information theory. The implications of these properties for the characterization of turbulent flow is discussed, including the implications for aspects of modeling these flows. To cite this article: S. Tardu, C. R.
