Abstract

a. Buse à fente annulaire destinée à la distribution d'un fluide en écoulement sur un fond, par exemple un fond sous un lit fluidisé. b. La buse comporte un canal 4 traversant le fond 1, un chapeau 5 qui recouvre le canal, en laissant libre une fente annulaire 7 entre lui-même et le fond, ainsi qu'une pièce de raccord 8 pour le maintien du chapeau, qui s'étend coaxIalement au canal à l'intérieur de ce dernier. Depuis la pièce de raccord jusqu'au bord de sortie 6 de la fente annulaire 7, s'étend une paroi 10 délimitant une chambre d'écoulement à symétrie de révolution. Cette dernière comprend la zone du canal 4, une zone de déflexion 9 et la fente annulaire 7. Toutes les parois délimitant cette chambre d'écoulement sont dimensionnées et disposées de sorte que la section de passage de la chambre d'écoulement diminue continuellement en direction de l'écoulement du fluide vers le bord de sortie de la fente annulaire.
