Abstract: Various implementations include a sweeping jet device with multidirectional output. The device includes an interaction chamber defined by a chamber wall. The chamber wall defines first and second inlet ports and first and second outlet ports. First and second fluid supply inlets are configured to introduce first and second inlet fluid streams through the first and second inlet ports, respectively, and into the interaction chamber. First and second outlet nozzles are configured to discharge first and second outlet fluid streams from the interaction chamber through the first and second outlet ports and the first and second outlet nozzles, respectively. The first and second inlet fluid streams collide within the interaction chamber causing the first and second outlet fluid streams to sweep as the first and second outlet fluid streams are discharged from the first and second outlet nozzles, respectively.

Abstract: Various implementations include a fluidic oscillator having at least one control port. The at least one control port is for introducing a control fluid into the fluidic oscillator or suctioning the fluid stream from the fluidic oscillator. The introduction of a control fluid into the fluidic oscillator or suction of the fluid stream from the fluidic oscillator alters the frequency and sweeping angle of the oscillating fluid stream as it exits the fluidic oscillator. Various other implementations include a fluidic oscillator having a first control port defined by the first portion of the outlet nozzle and a second control port defined by the second portion of the outlet nozzle. The introduction of a control fluid into the fluidic oscillator or suction of the fluid stream from the fluidic oscillator through the control ports alters the exit angle of the oscillating fluid stream as it exits the fluidic oscillator.

Abstract: Various implementations include fluidic oscillator devices with three-dimensional output. The devices define an inner channel having an interaction chamber, fluid supply inlet, outlet nozzle, and first and second feedback channels. The fluid supply inlet introduces a fluid stream into the interaction chamber. The fluid stream exits the interaction chamber through the outlet nozzle. The first and second feedback channels are in fluid communication with the interaction chamber. The walls of the interaction chamber are configured to allow fluid from the fluid stream to flow into the first and second feedback channels and to cause the fluid stream to sweep between the walls of the interaction chamber. The sweeping of the fluid stream between the wails of the interaction chamber causes the fluid stream exiting the outlet nozzle to sweep. The structure of the inner channel of the device causes the exiting fluid stream to sweep three-dimensionally.

Abstract: Various implementations include a feedback type and jet interaction-type fluidic oscillator devices with atomized output. The device includes first and second fluidic oscillators. Each of the first and second fluidic oscillators include an interaction chamber, a fluid supply inlet, an outlet nozzle, and first and second feedback channels. The first feedback channel of the first fluidic oscillator share a common intermediate portion such that the first feedback channels are in fluid communication with each other, causing the fluid streams exiting the outlet nozzles of the first fluidic oscillator and second fluidic oscillator to oscillate in phase with each other. The outlet nozzle of the first fluidic oscillator and the outlet nozzle of the second fluidic oscillator are structured such that the fluid streams exiting the outlet nozzle of the first fluidic oscillator and the outlet nozzle of the second fluidic oscillator collide with each other, creating an atomized spray.

Abstract: Various implementations include a fluidic oscillator array including at least two fluidic oscillators, each including an interaction chamber, fluid supply inlet, outlet nozzle, and feedback channels. The interaction chambers have a first and second attachment wall. Fluid streams flow from the fluid supply inlets, into the interaction chambers, and exit through the outlet nozzles. A feedback channel is coupled to each of the first and second attachment walls. Each feedback channel is in fluid communication with the interaction chamber and has an intermediate portion disposed between a first and second end of the feedback channels. Fluid from the fluid stream flows into the first ends of the respective feedback channels, causing the fluid stream to oscillate between the first and second attachment walls. Adjacent feedback channels of adjacent fluidic oscillators share a common intermediate portion, causing the exiting fluid streams of each fluidic oscillator to oscillate at the same frequency.
