Abstract
An improved fluidic device that operates on a pressurized liquid flowing through it at a specified flow rate to generate an oscillating spray of liquid droplets having desired properties (e.g., average spatial distribution, size, velocity, frequency and wavelength of liquid droplets at a defined distance in front of the device) includes: (a) a plurality of fluidic oscillators, each having a channel that is part of a fluidic circuit for inducing oscillations in the pressurized liquid that flows through the oscillator, (b) a housing having an exterior surface that includes a front face with a center-point and a rear face, (c) a plurality of passages, each of which extends through the housing and intersects with its front face to define an outlet, with each passages configured to allow for the insertion of one of the plurality of fluidic oscillators into each of the plurality of passages, and (d) a geometrical arrangement of these outlets in the housing front face that is chosen so as to achieve the desired properties of the oscillating spray when the device is operating at its specified flow rate.
