爆炸抛撒过程的研究进展

爆炸抛撒指含能材料爆炸产生的瞬时高压对周围介质产生驱动作用的过程,这种驱动方式在军事和民用工程中获得了广泛应用。整理了国内外涉及爆炸抛撒武器的研究资料,详细分析了爆炸抛撒在化学武器、FAE、灭火弹药、金属颗粒流毁伤元中的应用,从理论分析、数值仿真和试验研究等方面对爆炸抛撒过程的研究进行了综述,系统总结了爆炸抛撒过程中云雾范围、颗粒速度、尺寸、浓度和温度效应等主要参数的研究进展,归纳了各参数规律性的表现,提出了今后应该重点解决的问题和研究方向。

Review on Explosive Dispersion

The explosive dispersion is a driven process in which the instantaneous high pressure produced by energetic materials drive the surrounding medium, it was widely used in military and civil engineering. The research on Explosive dispersal weapons was summarized and the application of chemical weapons, FAE, fire extinguishing warhead and damage mode of metal particle flow were fully analyzed. The researches of explosive dispersal process were reviewed theoretically, numerically, and experimentally. Besides, the research progress of explosive dispersal range, particle velocity, size, concentration and thermal effects were summarized systematically and the problems and research directions on the explosion dispersion were proposed.
