【摘要】：利用商用磁流体力学模拟程序USIM对双等离子体团相互作用过程进行了数值模拟,分别考察和比较了双对流等离子体团在外加磁场和无外加磁场情况下,相互作用的物理过程.发现在外加磁场情况下等离子体团相互作用会伴随着磁重联(反向磁场)、磁排斥(同向磁场)以及一些不稳定过程.针对激光产生等离子体团错位相互作用实验,进行了标度模拟,发现外加磁场起着重要作用,进一步表明激光等离子体的磁化特征.研究结果为下一步在神光Ⅱ激光装置进行强磁环境下等离子体实验提供理论指导.
[Abstract]:The interaction process of double convection plasma clusters is numerically simulated by commercial magnetohydrodynamic simulation program USIM. The physical processes of the interaction of double convective plasma clusters in and without external magnetic field are investigated and compared respectively. It is found that the interaction of plasma clusters in an external magnetic field is accompanied by magnetic reconnection (reverse magnetic field), magnetic repulsive (isotropic magnetic field) and some unstable processes. In this paper, the scale simulation is carried out on the experiment of laser produced plasma group dislocation interaction. It is found that the external magnetic field plays an important role, which further indicates the magnetization characteristics of laser plasma. The results provide theoretical guidance for the plasma experiment in the Shenguang 鈪，
