Abstract: A fluid disperser is provided for dispersing a first fluid into a moving eam of a second fluid. After the first fluid is pressurized to at least twice the pressure of the second fluid, the first fluid is passed through a throat that increases the flow velocity of the first fluid to supersonic. A fluidic oscillator, coupled to the output of the throat, has a central axis of symmetry, a first end by which the first fluid enters the oscillator and a second end by which the first fluid exits the oscillator. The oscillator includes two opposing walls that diverge symmetrically about the central axis from the first to the second end at an angle of divergence relative to the central axis that causes the first fluid entering the first end to attach to either of the two opposing walls and continue therealong to the second end. The oscillator further includes feedback loops for feeding back a portion of the first fluid exiting the second end that is attached to either of the two opposing walls to the first end so that the first fluid will detach from one of the two opposing walls and attach to the other of the two opposing walls. First and second diverging nozzles, coupled to the second end of the oscillator, direct a remainder of the first fluid exiting the second end into the second fluid. specifically, each of the first and second diverging nozzles diverge symmetrically about and away from the central axis at approximately the angle of divergence. The first and second diverging nozzles terminate in a spaced apart relationship in the second fluid.

Abstract: A fluidic oscillator which is free of feedback passages has an oscillation chamber having a length greater than its width, a pair of mutually facing and complementary-shaped sidewalls, planar top and bottom walls, and first and second end walls. An input power nozzle is formed in said first end wall having a width W and a depth D, for issuing a stream of fluid into the oscillation chamber, and form alternately pulsating, cavitation-free vortices in said oscillation chamber on each side of the stream. An interconnect passage or channel proximate the downstream end wall enlarges the sweep angle and improves periodicity of the oscillations. The outlet wall is hingedly connected to a chamber wall and the chamber is such that it can be molded with the outlet wall hingedly connected thereto in one molding and forms one side of the interconnect passage or channel.

Abstract: A spray-forming output device for fluidic oscillators to provide relatively wide-angle three-dimensional output spray patterns is connected to the output of a fluidic oscillator. The device comprises mutually counter-directed conduits whose entry regions are fed from the oscillator output and whose exit regions are connected to an interaction outlet region that includes a common outlet, the common outlet being directed substantially orthogonally with respect to the plane in which the counter-directed conduits are disposed. In one embodiment, the interaction outlet region includes an impact wall disposed at the exit regions of the counter-directed conduits proximally to the common outlet. The spray-forming output device further comprises in one embodiment a shunt inertance conduit that provides an inertance shunt path between the entry regions of the counter-directed conduits, the shunt conduit being operative in smoothing out waveforms of the alternating flows from the oscillator and also providing for load-impedance matching between the oscillator and the output device. In operation, alternating output flows from the fluidic oscillator feed the counter-directed conduits and therefrom are deflected into the common outlet of the interaction outlet region. The alternating output flows mutually interact in the interaction outlet region and issue therefrom in the form of a substantially common fluid stream that oscillates or sweeps from side to side in correspondence with the oscillation of the fluidic oscillator.

Abstract: A fluid dispersal device utilizes alternately pulsating vortices to cyclically oscillate a fluid stream transversely of its flow direction in a desired flow pattern. A pair of pulsating fluid streams, which may issue from a fluidic oscillator are projected into an output region or chamber defined in a body member the output region or chamber having inlets for the pulsating fluid streams and at least one outlet opening with the outlet opening being positioned to issue pressurized fluid from the chamber into an ambient atmospher. Vortices formed in the chamber are alternately oppositely rotating and cause the flow pattern to cyclically sweep across the outlet. The vortices have axes normal to the direction of fluid flow and alternately spin in first and second directions in response to inflowing of the first and second pulsating fluid streams to the chamber and the output flow is cyclically swept back and forth as each vortex spins in the first and second directions respectively.

Abstract: A fluidic oscillator includes a chamber having a common inflow and outflow opening into which a jet is issued in a generally radial direction. After impinging upon the far chamber wall the jet is redirected to form a vortex on each side of the incoming jet. The vortices alternate in strength and position to direct outflow through the common opening along one side and then the other of the inflowing jet. A spray-forming output chamber is arranged to receive the pulsating outflows from the aforementioned or other fluid oscillator and establish an output vortex which is thereby alternately spun in opposite directions. An outlet opening from the output chamber issues fluid in a sweeping spray pattern determined by the vectorial sum of a first vector, tangential to the output vortex and a function of the spin velocity, and a second vector, directed radially from the vortex and determined by the static pressure in the chamber. By increasing or decreasing the static pressure, or by increasing or decreasing the vortex spin velocity, the angle subtended by the sweeping spray can be controlled over an unusually large range. By properly configuring the oscillator and/or output chamber, concentrations and distribution of fluid in the spray pattern can be readily controlled.

Abstract: A fluidic oscillating nozzle that oscillates a fluid jet at high frequency by the use of fluidic amplification technology with no moving parts. The jet that issues from the nozzle is a zero-degree jet of fluid that maintains a very high energy density; however, due to its oscillation, its appearance is that of a fan-type jet that disperses at a fan angle from the nozzle. At a nominal distance from the nozzle, the jet covers the surface with a relatively broad area of flow while maintaining high energy impact density due to the impact effects of the non-expanding zero-degree jet.

Abstract: 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.
