Abstract:
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.
