燃料破碎成液滴的过程很复杂,因此雾化细度主要用试验方法确定。在整理试验资料时,为了更广泛地综合试验数据,运用将与雾化特性有关的一些参数综合在一起的相以准则。对于气力式喷咀,在分析雾化细度与某几个参数的关系基础上,选定了对液滴尺寸影响最大的准П_7则[文献1]。此准则将雾化介质的能量消耗率 e_г=G_гW_г~2/B_T2g,气
The process of breaking the fuel into droplets is complicated, so atomization fineness is mainly determined by the test method. In compiling the test data, in order to more comprehensively synthesize the test data, a criterion is used that combines some of the parameters related to atomization characteristics together. For the pneumatic nozzle, based on the analysis of the relationship between atomization fineness and a few parameters, we selected the quasi-Pr7 which has the greatest influence on the droplet size [1]. This criterion will atomize the medium energy consumption rate e_г = G_гW_г ~ 2 / B_T2g, gas
