摘要： The fluidic oscillator (14) includes a resonant fluid circuit having a fluid inertance and a dynamic fluid compliance. The inertance is a conduit (4) interconnecting two locations (16a, 16b) of a chamber on each side of a working fluid jet issuing into one end of the chamber (3), the inertance conduit transfers working fluid between the two locations. Through one or more output orifices (10), located at the opposite end of chamber (3), the fluid exits from an exit region (11) which is shaped to facilitate formation of a vortex (the dynamic compliance) from the entering fluid. The flow pattern in chamber (3), specially the vortex in exit region (11) provide flow aspiration on one side and surplus of flow on the opposite side of chamber (3), which effects accelerate and respectively decelerate the fluid in the inertance conduit (4) such as to cause reversal of the vortex after a time delay given by the inertance. The vortex in the exit region will cyclically alternate in velocity and direction of rotation to direct outflow through the output orifice such as to produce a cyclically repetitive side-to-side sweeping stream whose direction is determined, at any instant in time, as a function of the vectorial sum, at the output orifice, of the tangential vortex flow spin velocity vector and the static pressure vector and the dynamic pressure component, both directed radially from the vortex. By changing these parameters and by appropriately configuring the oscillator, sweep angle, oscillation frequency, distribution, outflow velocity, break up into droplets, etc. can be controlled over large ranges.

摘要： A small, but nevertheless high-flow fluidic oscillator has a dual level body portion including an interaction chamber in a first level. An inlet plenum supplies fluid to a supply nozzle which enters directly into the inlet end of the interaction chamber to direct a jet flow from the supply nozzle, through the interaction chamber and out of an outlet opening. A fluid passage is located at least partly in the second level of the body portion, and connecting passages on either side of the supply nozzle connect the fluid passage to the inlet end of the interaction chamber. The walls of the interaction chamber converge from the inlet end toward a neck portion and thereafter diverge and then converge again at the outlet so that a fluid column extends between the jet flow and the sidewalls of the interaction chamber, and moves cyclically back and forth through the fluid passage and the connecting passages to obtain interaction between the fluid column and the jet flow without the need for control nozzles.

摘要： L'oscillateur a fluide comprend un circuit resonnant ayant un element d'inertie au fluide et une adaptation dynamique au fluide. L'element d'inertie est un conduit (4) reliant deux points ou positions (16a, 16b) d'une chambre de chaque cote d'un jet d'un fluide de travail debouchant dans une extremite de la chambre (3), le conduit d'inertie transferant le fluide de travail entre les deux points. Au travers d'un ou plusieurs orifices de sortie (10), situes a l'extremite opposee de la chambre (3), le fluide sort par une zone de sortie (11) qui est faconnee pour faciliter la formation d'un vortex (l'adaptation dynamique) avec le fluide d'entree. Le modele d'ecoulement dans la chambre (3), specialement le vortex dans la region de sortie (11) donne une aspiration d'ecoulement d'un cote et un surplus d'ecoulement du cote oppose de la chambre (3), dont les effets accelerent et ralentissent respectivement le fluide dans le conduit d'inertie (4) provoquant l'inversement du vortex apres un temps de temporisation donne par l'inertie, Le vortex dans la region de sortie alterne cycliquement la vitesse et le sens de rotation pour diriger l'ecoulement de sortie au travers de l'orifice de sortie de maniere a produire un courant de balayage d'un cote a l'autre, cycliquement repetitif, dont la direction est determinee, a tous moments, en fonction de la somme vectorielle, a l'orifice de sortie, du vecteur vitesse de rotation de l'ecoulement du vortex tangentiel et le vecteur pression statique ainsi que la composante de pression dynamique, tous deux diriges radialement par rapport au vortex. En changeant ces parametres et en donnant une configuration appropriee a l'oscillateur, l'angle de balayage, la frequence d'oscillation, la distribution, la vitesse d'ecoulement de sortie, l'eclatement en gouttelettes, etc. peuvent etre commandes sur de grandes plages de valeurs.
