摘要: 在一维有限差分反应流体动力学程序SSS中引入电爆炸模型,在此基础上结合新引入的物态方程库,开展了电爆炸加载下飞片运动过程的数值模拟研究。计算结果与实验结果基本吻合,表明SSS对电爆炸驱动飞片的过程的模拟是可靠的,为电炮加载技术的优化设计和电爆炸驱动飞片物理过程的进一步研究提供了一套有效的计算方法和程序。Abstract: We modified the one-dimensional hydrodynamic code named SSS for simulation of acceleration of Mylar flyer driven by electric explosion. Both simulated histories of discharging current and flyer are consistent with those of experimental results, which validates that the hydrodynamic code SSS with this new introduced model is reliable to simulate the electric explosion. The presented work will be much more helpful for understanding the physical process of electric explosion and optimization of the electric gun instrument itself.
