[Characterization of unsteady time periodical turbulent flows]
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.
Le lien est établi entre les écoulements turbulents instationnaires à périodicité imposée et les processus cyclostationnaires (PCS) largement traités dans le domaine de la théorie de l'information. Les implications de ces propriétés dans la caractérisation des écoulements turbulents sont discutées, y compris pour des aspects de modélisation.
