:为寻求旋流组合式喷嘴雾化性能影响因素间的优化匹配方案,在分析和总结的基础上,选取旋流器的组合方式、喷头构型、进气流量和进气方式等作为主要影响因素,通过正交设计理论,安排试验方案,采用相位多普勒粒子分析仪(PDPA)对雾化性能的关键评判因素--喷雾场粒径进行了采集测量.实验结果的极差分析和方差分析表明,旋流器的组合方式对雾化粒径的影响最强,水流量次之,再次为喷头构型,而进气方式的影响最弱;此外,旋流器组合方式与喷头的交互作用产生的影响不应被忽略.

With the effective factors of flow distribution characteristics of the combined swirl feeding spray nozzle,test schemes were established using the orthogonal experiment design (OED),and the Phase Doppler Particle Analyzer (PDPA) was used to determine the liquid drop size,one of the most deceive parts in the flow distribution characteristics. Range analysis and variance analysis of numerical results showed that the different cyclones combination form had biggest impact on the liquid drop size. The mass flow rate of water played a more important role than the structure of nozzle dose. In addition,the interaction of cyclones distribution combination form with structure of nozzle should not be ignored.
