Ecoulement tridimensionnel dans le sillage d'un cylindre placé dans une couche de mélange plane

Abstract : In this study, we analyse the wake of a circular cylinder embedded in a plane mixing layer. Investigation was carried out involving miniature four hot wire probes. The Reynolds number was in the range 6000-9000. Through the analysis of the mean velocities we could observe a singular behaviour of the wake in that highly tridimensional complex flow. Spectral analysis gave informations on the spatial organization of the flow. Confirmations were drawn from the study of the Reynolds stresses.
