1. A fluidic oscillator device with atomized output, the device comprising:
at least two fluidic oscillators, the at least two fluidic oscillators including a first fluidic oscillator and a second fluidic oscillator, each of the first fluidic oscillator and second fluidic oscillator comprising:
an interaction chamber having a first surface, a second surface opposite and spaced apart from the first surface, an interaction chamber plane being disposed equally distanced from the first surface and the second surface, and a first attachment wall and a second attachment wall extending between the first surface and the second surface, the first attachment wall and the second attachment wall being opposite and spaced apart from each other,
a fluid supply inlet for introducing a fluid stream into the interaction chamber,
an outlet nozzle downstream of the fluid supply inlet, wherein the fluid stream exits the interaction chamber through the outlet nozzle, and
a first feedback channel coupled to the first attachment wall and a second feedback channel coupled to the second attachment wall, the first feedback channel and second feedback channel being in fluid communication with the interaction chamber, each of the first feedback channel and second feedback channel having a first end, a second end opposite and spaced apart from the first end, and an intermediate portion disposed between the first end and second end, wherein the first end is adjacent the outlet nozzle and the second end is adjacent the fluid supply inlet, wherein the first attachment wall and second attachment wall of the interaction chamber are shaped to allow fluid from the fluid stream to flow into the first ends of the first feedback channel and second feedback channel, respectively, causing the fluid stream to oscillate between the first attachment wall and second attachment wall of the interaction chamber;
wherein the first feedback channel of the first fluidic oscillator and the first feedback channel of the second fluidic oscillator share a common 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, and
wherein 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 continuously collide with each other.
