The labyrinth seals are the devices used in rotating machinery, they serve to restrict the leakage flow crossing a carter by a rotating shaft and to avoid the important friction at high rotating speeds. These devices can modify the dynamic characteristics of the line of the shaft in which they are integrated. The present work allows determining the effect of physical parameters on the dynamic coefficients. The object of this work consists to better control the flows within labyrinth seals and to be a better the stability of machinery.

Abstract
The labyrinth seals are the devices used in rotating machinery, they serve to restrict the leakage flow crossing a carter by a rotating shaft and to avoid the important friction at high rotating speeds. These devices can modify the dynamic characteristics of the line of the shaft in which they are integrated. The present work allows determining the effect of physical parameters on the dynamic coefficients. The object of this work consists to better control the flows within labyrinth seals and to be a better the stability of machinery.

Abstract: (french)
Les joints labyrinthes sont des dispositifs utilisés dans les machines tournantes, ils servent à limiter le débit de fuite à la traversée d’un carter par un arbre tournant et éviter le frottement important aux vitesses de rotation élevées. Ces dispositifs peuvent modifier les caractéristiques dynamiques de la ligne d’arbre dans laquelle ils sont intégrés. Le travail présenté permet de déterminer l’influence des paramètres physiques et géométriques sur les coefficients dynamiques de raideur et d’amortissement. Le but de ce travail consiste à mieux maîtriser les écoulements dans ces types de joints et avoir une meilleure stabilité des machines.
