摘要: 根据磁场、电流密度和感应电流的解析公式研制了爆炸磁通压缩发生器充电和爆磁压缩过程的计算程序MFCG Ⅱ。在相同条件下用该程序和二维磁流体力学程序MFCG Ⅰ分别计算相同模型所得结果符合较好。因此用MFCG Ⅱ可分析、解释MFCG实验中有关的物理问题。Abstract: In this paper, computational code MFCG Ⅱ of the explosive magnetic field compression generator (MFCG) are developed based on the analytic formulas of magnetic field, current intensity and induced current for the process of charge and compression. Under the same conditions, computational results obtained by 2-D MHD MFCG Ⅱ code coincide with those obtained by 2-D MHD MFCG Ⅰ for the patterns of same parameters. Therefore , the concerned physical problems can be analysed and explained by MFCG Ⅱ in MFCG tests.
