摘　　要：为研究气动扇形喷嘴雾化特性,设计加工了不同角度、不同出口形式和不同尺寸的5种扇形喷嘴,并搭建了试验台架系统,进行了喷嘴雾化试验。根据试验测量结果,从流量特性和雾化特性方面分析了气液比、喷嘴结构等对喷嘴流量系数、喷雾场雾化粒径分布的影响,并定性给出了喷嘴结构对雾化特性的影响规律。To study the atomization characteristics of fan spray nozzle,five fan spray nozzles with different spraying angle,different outlet form and different size were designed.An experimental bed system was built.The spraying experiment for the nozzles was performed under the design conditions.In the aspects of mass flow and atomization characteristics,the influence of gas-liquid ratio and nozzle structure on flow coefficient of nozzle and distribution of atomization particles was analyzed.The qualitative influence trend of nozzle structure on atomization characteristics is given.
