| 摘 要： | 介绍一种气体发生剂高压燃气驱动的高速液体喷洒装置,利用高速摄影和压力测试系统,研究了安装螺旋喷嘴的喷洒装置在不同装药量下的喷射初始速度和液体雾化射流的扩展过程。实验结果表明,气体发生剂装药量大于50 g时,喷洒装置可快速形成稳定的喷雾锥,随着药量的加大,喷嘴的雾化效果也显著提高。并发现气/液界面的Rayleigh-Taylor(RT)不稳定性会对喷嘴的正常工作带来不良影响。

| Abstract: | A new spray device is presented in the paper.Its power source is burned gas produced by combustion of gas generation compositions.High-speed photography was used in the experiments.Atomization processes of spiral jet spray nozzles is studied under five different charge quantities(30 g,40 g,50 g,70 g,90 g) of gas generator.Experimental results show,the atomizing effect of jet can be improved with increasing charge quantity of the main propellant grains.When charge quantity of gas generator is more than 50 g,the atomizing effect of jet is preferable. |
