摘　　要：高速运动液体的爆炸抛撒研究对于爆炸水雾除尘,灭火航弹以及云爆弹等技术的发展有着重要的意义,利用真实场景实验研究耗资巨大,且不易测量.针对如何在实验室内开展动态高速液体云雾抛撒模拟实验研究的问题,开发出轻气炮加载,撞击式高速云雾抛撒实验装置.实验结果表明该装置客观真实地反映出了液体云团动态抛撒的发生发展过程.Study of explosive dispersion of high-speed moving liquid have important technique significance for the dust-reduction of blasting water mist,air extinguishing bomb and fuel air explosive.And it is expensive and difficult to measure by using real mechanism.In order to carry out simulation experiments on dynamic and high-speed liquid cloud spraying in the laboratory,a laboratory experimental apparatus was developed,which accomplish the experiment by using the light gas gun as loading device,the impact needle impacting the high-speed liquid.The experimental results had shown that the apparatus can reflect the dynamic process of high-speed moving liquid dispersion.
