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。
In order to study the penetrating characteristics of a Y-shaped nozzle, an experimental bench system was set up, the working parameters of the nozzle were designed, and the cold state experiment of the nozzle was carried out. Based on the experimental results, the effect of gas-liquid ratio (2% ~ 4%) on the penetration depth was analyzed. A new type of non-dimensional composite momentum was proposed. The MYLeong penetration depth empirical formula was improved and the experimental Under the conditions of empirical parameters. The penetration depth of the nozzle is further calculated and analyzed using the mathematical model of droplet movement.
