Abstract

Dispositif d'influencement des couches limites sur des parois d'appareils de conduite de flux de préférence gazeux. Les parois 10 de ce dispositif 1, 2 comportent de fins perçages 16 qui sont reliés à des canaux collecteurs 11-15, 21-25 intérieurs à elles et servant à l'aspiration ou à l'amenée commandées de gaz. L'invention s'applique notamment à des tuyères ou diffuseurs pour la séparation d'isotopes avec excitation sélective par laser.
