| 摘 要： | 在调研跟踪国外磁化套筒惯性聚变(MagLIF)研究领域最新进展的基础上，以一维磁流体力学方程为基础，结合氘氚燃料能量交换方程，建立一维磁化套筒惯性聚变物理模型，并使用Fortran语言编写完成一维数值模拟程序MagLIF-1D；通过与圣地亚实验室LASNEX,HYDRA等程序计算结果对比展示，完成程序校验工作，讨论后认为程序计算结果存在差异的主要原因可能来自不同程序对于材料状态方程库的选择；通过计算，MagLIF-1D程序可以直接获得内爆速度、燃料压力、燃料密度、聚变产额等关键物理量，这为后续更好地开展磁化套筒惯性聚变实验设计提供了有力工具。

| Abstract: | Combining PTS facility and magnetized linear inertial fusion (MagLIF) research, 1D simulation code MagLIF-1D was programmed based on MHD theory and DT fuel energy equations. Most challenges came from solving difficulties on boundary coupling, and its convenient to acquire key parameters such as liner velocity, magnetic field strength, fuel density and fusion yield directly from calculated output. Foundational comparisons with LASNEX and HYDRA codes were made to verify the MagLIF-1D code, and differences were discussed and analyzed. The achievements are substantial foundations for further exploring about MagLIF technology, and the calculated results are valuable for future experimental performance. |
