内爆磁通量压缩过程的一维磁流体计算及分析
One-Dimensional Magneto-Hydrodynamics Calculation and Analysis of Implosion Magnetic Flux Compression Process
摘要
Abstract
In this work we modified the 1D implosion and the MHD code-MC11D by introducing the equation of state (EOS) in analytical form into the program.Then,using the modified code,we simulated a cylindrical implosion magnetic flux compression experiment on the copper sample and obtained the velocity histories of the sample tube's inner wall,the p-V lines of the copper sample,and the temperature histories of the material.The results from our simulation are closely consistent with those simulated with the original code using the tabular EOS database.In addition,the velocity curves obtained from the simulation are also found to accord with the experimental result.Our work expands the application scope of the MC11D code.Using the modified code,the materials which are not included in the tabular EOS database can also be simulated.It will serve as a useful method for the analysis of experimental results and data processing.关键词
