| 摘 要： | 基于电流和磁扩散方程,讨论了螺旋型爆磁压缩脉冲发生器(MFCG)中的电阻与磁通损耗问题,将相关的接触电阻模型、欧姆电阻的趋肤效应与邻近效应模型具体应用到2维爆轰磁流体力学程序MF-CG-Ⅳ中,进一步完善了程序的物理功能。并选用美国德克萨斯理工大学简单绕制的螺旋型爆磁压缩脉冲发生器的实验结果对新增模块进行了考证,计算结果符合物理规律,且与实验测量吻合较好。

| Abstract: | Systematic study is done on problems of resistance and flux losses in helical magnetic flux compression generator(MFCG) based on current equation and magnetic diffusion equation. The program MFCG-Ⅳ is extended by considering contact resistance model, and ohmic resistance model based on skin depth and neighboring interaction model. Using the experimental parameters of Texas Tech University(TTU), comparable numerical results with the experimental ones are derived, which can depict the physical phenomena. |
