柴油压力喷射破碎特性试验研究

在压力喷雾试验中，观测到了一些液雾破碎现象：在喷嘴出口处，液射流旋转；液射流的完全破碎并不发生在与喷雾轴线相垂直的径向截面内，而是发生在某一螺旋截面上。据此作者提出了一种液射流破碎的物理模型。试验中还发现了一种新的破碎长测量方法，本文报告了这些试验结果。

An Experiment Study on the Break Characteristics of Diesel Fuel Injection by Pressure

Some breakup phenomena of fuel injection by pressure,such as spray rotation at jet exit,that complete breakup did not occur at the spray radial section but along spiral,were observed in an injection experiment.From that,a physical model on the breakup of fluid injection was proposed.A new measurement method on breakup length was also discussed.
