摘要: 给出了电爆炸丝1维磁流体模型的具体描述和基本方程，并利用数值方法求解。通过对含电爆炸丝断路开关的电感储能脉冲功率电路模型的计算，给出了电爆炸丝电流、电压随时间的变化，以及电爆炸过程中丝的密度空间分布，膨胀半径随时间的变化，讨论了电爆炸丝长度和初始电压对电爆炸丝电流、电压的影响。Abstract: 1D magnetohydrodynamics (MHD) model is used to describe the explosion of electric explosive wires. Using numerical method, the results about electric current of circuit, the voltage of electric explosive wires vs time, and the density, current density vs r are given. The relation between the length of explosive wires, the voltage of caption and the electric current, the voltage of electric explosive wires are discussed.
