摘要
采用高速摄像法记录水在爆炸作用下的抛撒过程,研究了不同爆炸水袋长径比对水爆炸抛撒成雾运动的影响。通过对实验记录数据的分析,获得了在不同的长径比条件下,水爆炸抛撒过程中的径向半径、径向速度以及水雾轴向高度与时间的关系曲线,同时还对水雾运动的特性和形状做了定性分析。结果表明:水袋长径比对抛撒水雾的径向半径、轴向高度影响不大,但长径比是影响水雾径向抛撒初速度的重要因素。
The dispersal process of water mist is recorded by high-speed photography, and the influences of the different ratio of length to diameter of explosive water bag on the kinetic characteristics of mist dispersal, which is resulted from explosion, is researched. After analyzing the experirnental data, the curves of the radial dispersal radium, radial dispersal velocity and axial dispersal height of the water mist against time during water dispersion are obtained, at the same time, the kinetic characteristics and the forms of water mist are qualitatively analyzed as well. The results indicate that the ratio of length to diameter hasn＇t obvious effect on radial dispersal radium and axial dispersal height, but is the main factor influencing on the original radial dispersal velocity.
