| 摘 要： | 为研究柱形装药水中爆炸气泡射流特性,采用高速摄影方法在实验水箱中对PETN药柱进行水中爆炸实验,初步获得了有关柱形装药自由场水中爆炸气泡运动的数据资料.研究结果表明:柱形装药自由场水中爆炸形成气泡的运动与球形装药的存在差别,药柱放置方式的变化也会导致水中爆炸气泡产生性质迥异的运动.当药柱水平放置时,气泡表面的运动呈非对...

| Abstract: | Underwater explosion experiments were carried out for PETN cylinders in a water tank and elementary data about bubble motions under free-field conditions were obtained by using the high-speed photography technology.Results show that the bubble dynamics of cylindrical charges differs from those of spherical ones,and charge mounting modes affect markedly bubble behaviors.For a horizontally mounted cylindrical charge,asymmetric collapse is achieved due to the asymmetric motion of the bubble interface.As a resu... |
