| 摘 要： | 作者在详细介绍了衬套内爆二维磁流体(MHD)力学模拟的ALE方法的基础上，运用算子分裂技术将MHD力学方程组分裂成热扩散、磁扩散、Lagrangian流动、网格生成和对流输运4步求解.作者对Frese等人的Lagrangian流动步方法进行了改进，消除了其拉氏计算的质量损失.编制了二维计算程序并通过验证，获得的二维衬套内爆不稳定性发展与Doughlas和Liberman等人的结果相吻合.

| Abstract: | An arbitrary Lagrangian-Eulerian(ALE) simulation of 2D magnetohydrodynamic(MHD) for a liner is presented.The physical model is devided into thermal and equilibrium radiation diffusion,resistive diffusion,Lagrangian hyhrodynamics,coordinate system motion and convetive transport by a time-split.The formulation of Lagrangian hydrodynamics introduced by Frese et al.is modified to preserve the conversation of mass in Lagrangian hydrodynamics step.The simulation results of some initial perturbations agree with these in the Douglas et al and Liberman et al paper. |
