Abstract

A fluidic oscillator (2) suitable for use at colder temperatures for utilizing a pressurized liquid to generate a uniform spatial distribution of droplets has (a) an inlet (28) for the pressurized liquid, (b) a set of three power nozzles (24) that are fed by the pressurized liquid, (c) an interaction chamber (26) attached to the nozzles and which receives the flow from the nozzles, wherein this chamber has an upstream (26a) and a downstream (26b) portion, with the upstream portion having a pair of boundary edges (26c, 26d) and a longitudinal centerline (26e) that is approximately equally spaced between the edges, and wherein one of the power nozzles (24) is directed along the chamber's longitudinal centerline (26e), (d) a throat (30) from which the liquid exhausts from the interaction chamber (26), and (e) an island (24) located in the interaction chamber, with this island being situated downstream of the power nozzle (24) that is directed along the chamber's longitudinal centerline (26e).
