摘　　要：为研究某Y型喷嘴的穿透特性,搭建了实验台架系统,设计了喷嘴的工况参数,并进行了喷嘴的冷态实验研究。根据实验测量结果,分析了气液比（2%~4%）对穿透深度的影响规律,提出了新型的无量纲复合动量,对M.Y.Leong穿透深度经验公式进行了改进,拟合了实验条件下的经验参数。进一步利用液滴运动数学模型对喷嘴的穿透深度进行了计算和分析。To research the penetration performance of Y-shape nozzle,the experimental system was built,the working parameters of the nozzle were designed and the cold test was conducted under the design conditions.The influence of air-liquid ratio（2%~4%）on the penetration depth was analyzed according to the experiment results.The novel dimensionless complex momentum was presented.M.Y.Leong experiential formula was improved base on the new nondimensional multiple momentum.The experiential parameters was fitted under the experimental condition.All the more,the mathematics model of kenetic droplet was calculated and analyzed.
