Research of Resonator-sound-generator Atomizing Nozzle [PDF]
, 2015 喷嘴技术的应用范围几乎包含所有工业领域、农业生产、交通运输以及人们的日常生活。作为必备组件在燃烧装置上的应用尤为重要。以往对于新型的流体动力式超声波雾化喷嘴研究表明：这类喷嘴的雾化粒径小（小于50μm）且分布均匀性好，对实现低氧燃烧、减少烟气中烟尘和氮氧污染物的排放有实质性的意义。因此本文以谐振腔式声能雾化喷嘴为研究对象，通过设计结构，利用FLUENT软件对其流场、声场以及雾化性能进行多参数的数值模拟，通过雾化性能的变化规律分析了其雾化机理。 研究首先基于哈特曼发声哨的原理设计了谐振腔式声能雾化喷嘴 ...
