Patent

CA 2239413

According to the process of the invention, a surface for contact with a fluid which flows over the surface in a direction (A) has grooves (1) to prevent burbling at low local Reynolds numbers; said grooves (1) extend between a closed entry upstream and an open outlet downstream and are directed obliquely to the direction of flow (A) at least in the region of the groove inlet.

L'invention concerne un procédé de réalisation d'une surface permettant le contact avec un fluide qui s'écoule au-desus de la surface dans un sens d'écoulement (A). Ce procédé se caractérise en ce que pour empêcher les décollages de courant en cas de nombres de Reynolds locaux bas, la surface est munie de rainures (1) qui s'étendent entre une entrée fermée dirigée en amont et une sortie ouverte dirigée en aval, et sont orientées obliquement par rapport au sens d'écoulement (A) au moins dans la zone d'entrée des rainures.
