This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lorsqu'une cavité est soumise à un écoulement turbulent, de forts niveaux sonores peuvent être engendrés. Pur évaluer les niveaux de pression acoustique en champ lointain une approche en deux étapes est proposée. Tout d'abord, des simulations numériques de l'écoulement, considéré comme incompressible, sont réalisées à partir des équations de Reynolds complétées par des lois de fermeture élémentaires (k-c, sgs Smagorinsky). En outre, des visualisations et des mesures de pression fluctuante pariétale sont réalisées en tunnel hydraulique ; ces mesures ne sont pas suffisamment exhaustives pour conduire à une validation totale des modèles numériques dont on a pu cependant repérer certaines lacunes, En conséquence, on a plutôt cherché à combiner les résultats issus de ces modèles et les données expérimentales pour constituer des données d'entrée cohérentes du modèle acoustique correspondant à la deuxième étape. Ensuite, un modèle acoustique simple, fondé sur l'analogie de Lighthill, permet le calcul de la fréquence et de l'amplitude de pression acoustique en champ lointain. Pour tester ce modèle, on s'appuie par ailleurs sur des mesures acoustiques en champ lointain réalisées dans une soufflerie anéchoïque. Le modèle acoustique fournit un ordre de grandeur très satisfaisant des niveaux de pression acoustique mesurés. Enfin, un développement annexe de ce travail a consisté à raffiner la typologie des écoulements dans les cavités lorsque le rapport géométrique L/H augmente. On distingue alors trois configurations d'écoulement. Pour une cavité carrée, l'écoulement est quasi-2D. Pour un rapport géométrique de l'ordre de 1,5, l'écoulement fortement 3D se caractérise par une ondulation transverse de la zone de recirculation principale. Enfin, pour des rapports géométriques supérieurs à 2, la zone de recirculation se concentre sur la partie aval de la cavité ; l'écoulement est alors 2D.
