%X 为明确喷嘴的设计方法和喷嘴结构对喷嘴性能的影响规律，本文对喷嘴的设计方法进行了梳理验证并研究了旋流半径比、旋流室倾角和喷孔长径比对喷嘴性能的影响规律：旋流半径比增大会使雾化角减小、流量增大；旋流室倾角增大会使雾化角增大、流量减小；喷孔长径比增大会使雾化角减小，对流量影响不大；喷孔长径比对雾化角影响最大，旋流室倾角对流量影响最大。<br />
In order to clarify the design method of nozzle and the influence of nozzle junction structure on nozzle performance, this paper combs and verifies the design method of nozzle, and studies the influence of swirl radius ratio, cyclone chamber inclination angle and nozzle length-diameter ratio on nozzle performance: increasing the swirl radius ratio will reduce the atomization angle and increase the flow. Increasing the inclination angle of the swirl chamber will increase the atomization angle and reduce the flow rate. The increase of the length-to-diameter ratio of the nozzle will reduce the atomization angle and have little effect on the flow; the length-to-diameter ratio of the nozzle has the greatest influence on the atomization angle, and the inclination angle of the swirl chamber has the greatest influence on the flow rate.
