Title (EN) NOZZLE CAPABLE OF DEVIATING A SYNTHETIC JET IN A DYNAMIC AND CONTROLLABLE MANNER WITH NO MOVING MECHANICAL PARTS AND A CONTROL SYSTEM THEREOF.
(FR) BUSE PERMETTANT DE DÉVIER UN JET SYNTHÉTIQUE DE MANIÈRE DYNAMIQUE ET CONTRÔLÉE SANS PIÈCES MÉCANIQUES MOBILES, ET SON SYSTÈME DE COMMANDE
Abstract:
(EN) A nozzle (1) is capable of producing a mixing of two primitive fluid jets (2) and (2') and a selective and controllable angular deviation of the synthetic jet (7) obtained by mixing the primitive jets without any moving mechanical part. The nozzle (1) is also capable of generating a controllable deviation of the synthetic jet and of changing the direction of this jet in a continuous and dynamic manner so as to allow the jet to sweep a preset and arbitrary angle. The nozzle (1) is constituted, in a first part thereof, by a conduit (8) divided into two channels by a central baffle (9) and, in a second part thereof, by a convergence zone and an outflow mouth (5) whose walls have a curvilinear profile and are connected seamlessly to the walls of the conduit.
(FR) L'invention concerne une buse (1) capable de produire un mélange de deux jets primaires de fluide (2) et (2') avec une déviation angulaire sélective et contrôlée du jet synthétique (7) obtenu par le mélange des jets primaires, sans recours d'une quelconque pièce mécanique mobile. La buse (1) peut également produire une déviation contrôlée du jet synthétique et modifier la direction de ce jet de manière continue et dynamique pour qu'il opère le balayage d'un angle prédéterminé et arbitraire. La buse (1) est constituée, dans une première partie, d'un conduit (8) divisé en deux canaux via un déflecteur central (9) et dans une seconde partie, par une zone de convergence et une bouche de sortie (5) dont les parois présentent un profil curviligne et qui sont reliées sans interruption aux parois du conduit.
