Atomizing devices (40, 60, 70, 80, 94) are provided that form droplets through the Rayleigh breakup mechanism. Various embodiments include one or more of the following features. Liquid orifices (48) form jets of liquid that form droplets. Gas orifices (46) provide gas coflow that inhibits coalescence of the droplets. The liquid orifices (48) can have non-circular cross-sectional shapes to promote Rayleigh breakup. Fluidic oscillators (101) can also be provided to promote Rayleigh breakup. Supply networks (58, 50, 52, 60, 54, 56) are provided to supply gas and liquid to the gas and liquid orifices (46, 48), respectively.
L'invention concerne des dispositifs d'atomisation qui forment des gouttelettes selon le mécanisme de rupture de Rayleigh. L'invention traite aussi de divers modes de réalisation présentant une ou plusieurs des caractéristiques suivantes. Les orifices de liquide forment des jets de liquide qui constituent des gouttelettes. Des orifices de gaz fournissent un écoulement de gaz qui inhibe la coalescence des gouttelettes. Les orifices de liquide peuvent présenter des formes non circulaires en section transversale pour favoriser la rupture de Rayleigh. Des oscillateurs fluidiques sont également prévus pour favoriser la rupture de Rayleigh. Des réseaux d'alimentation permettent de fournir du gaz et un liquide aux orifices de gaz et de liquide, respectivement.
