| 摘要: |
| 采用自行设计的两相喷雾实验设备和测量装置，通过MF激光散射测粒仪，对液氧液氢火箭发动机所用量气液同轴离心式喷嘴后方喷雾液滴的平均直径 MMD 和液滴尺寸分布指数n等雾化特性，进行了试验研究，测量了A型喷嘴在不同气体和液体喷注压降、不同空间位置的喷雾特性。分析了气体喷注压降一定时液体喷注压降对雾化特性的影响规律，以及当液体喷注压降一定时气体喷注压降对雾化特性的影响规律，得出了一些有意义的结论。研究结果对气液同轴离心式喷嘴设计有一定的指导意义。 |

| Abstract: |
| In this paper, an experimental investigation on spray characteristics of coaxial swirling injector was performed using the laser-scattering system (Malvern) and the self-designed atomization and sprays test facility. It was analyzed and discussed that the effect of gas injecting pressure differential on the spray mass median diameter (MMD) and spray diameter size distribution exponent (n). The study results should provide theoretic guidance in on going gas-liquid coaxial swirling injector design. |
