Title (EN) METHOD FOR HYDRODYNAMIC PROCESSING A SURFACE AND DEVICE FOR CARRYING OUT SAID METHOD
(FR) PROCEDE DE TRAITEMENT HYDRODYNAMIQUE DE SURFACES ET DISPOSITIF PERMETTANT SA MISE EN OEUVRE
Abstract: front page image
(EN)The inventive method consists in acting upon the area of the processed surface by at least two cavitating pressure water jets, said action being carried out in such a way that the cavitating jets cross each other. The inventive device comprises at least two nozzles. A distance L between the longitudinal axis of the nozzles is selected according to a relation 25 tg($g(a)/2) $m(F) L/d$g(F)$m(F)60 tg($g(a)/2), wherein $g(a) is the angle of divergence of a cavitating jet, d$g(F) is a nozzle diameter. Said invention makes it possible to increase the processing performance, improve the processing uniformity for the entire surface, increase the concentration and uniformity of cavitating bubbles in the processed area and to reduce operation pressure.
(FR)L'invention a trait à un procédé qui consiste à appliquer au moins deux jets d'eau cavitants sous pression sur une zone d'une surface à traiter, les jets cavitants se croisant lors de leur application. L'invention concerne également un dispositif comprenant au moins deux buses. La distance L séparant les axes longitudinaux des buses est sélectionnée de manière qu'elle soit conforme au rapport 25 tg($g(a)/2)$m(F)L/d$g(F)$m(F)60tg($g(a)/2), $g(a) représentant l'angle d'élargissement du jet cavitant, et d$g(F) représentant le diamètre d'une buse. Le procédé et le dispositif selon l'invention permettent d'augmenter l'efficacité du traitement, d'améliorer la régularité du traitement d'une surface complète, d'augmenter la concentration et de garantir la régularité des bulles de cavitation dans une zone d'une surface à traiter, et de diminuer la pression d'utilisation.
