Abstract

L’invention propose un conduit (28) de guidage de l’écoulement d’un flux (F1) d’un gaz, comportant au moins un tronçon amont (16) d’amenée du flux de gaz, caractérisé en ce que la paroi interne(24) du tronçon amont (16) comporte au moins une surface de perturbation (30) faisant saillie à l’intérieur du conduit (28) pour créer une turbulence dans le flux de gaz atteignant la surface de perturbation (30) selon une direction (D) sensiblement oblique à la direction de l’écoulement dans le tronçon amont (16). La surface de perturbation (30) appartient à une ailette de perturbation agencée à l’intérieur du conduit. Figure pour l'abrégé : 3
