摘要
本文得到了一些实验结果。从这些实验结果,得到喷射的射流雾化的物理原因可能是在喷管压力室内的压力能的聚集,它导致雾的猝发。至少这是一个主要的原因。此外,笔者提出了若干新的概念和考虑了针阀和压力室形状对射流雾化的影响。并证明了雾的分布符合Rayleigh分布。
In this paper,we obtain some experimental results. From these results, we obtain that the physical reasons for atomization of a jet spray may be the concentration of pressure energy in the pressure chamber of spray tube, which introduce the fog to burst. It is a principal reason at the least. In addition, we suggest some new concepts and consider the effect of the shape of pin valve and pressure chamber on the atomization of a jet. And we prove that the distribution of fog is conformed Rayleigh distribution.
