| 摘 要： | 本文应用调Q红宝石激光全息照相技术,对轴针喷嘴的燃油喷雾特性进行了研究,证实了喷雾初始段内部存在一个空心的内区,并在广安博之的孔式喷雾分裂长度公式的基础上,提出了应用于轴针喷嘴喷雾的准分裂长度半经验公式,同时还对粒径的空间分布特性进行了测定分析.

| Abstract: | The diesel sprays injected from pintle nozzles were observed by Q-switchead ruby laser holography. It was proved that there is a hollow conical region in the fuel spray at the early stage of injection. A semi-empirical relationship is proposed based on the modification of the Hiroyasu's expression to calculate the breakup length of the pintle nozzle spray. The droplet size distribution for the spray has also been investigated experimentally. |
