【摘要】：利用商用磁流體力學模擬程序USIM對雙等離子體團相互作用過程進行了數(shù)值模擬,分別考察和比較了雙對流等離子體團在外加磁場和無外加磁場情況下,相互作用的物理過程.發(fā)現(xiàn)在外加磁場情況下等離子體團相互作用會伴隨著磁重聯(lián)(反向磁場)、磁排斥(同向磁場)以及一些不穩(wěn)定過程.針對激光產生等離子體團錯位相互作用實驗,進行了標度模擬,發(fā)現(xiàn)外加磁場起著重要作用,進一步表明激光等離子體的磁化特征.研究結果為下一步在神光Ⅱ激光裝置進行強磁環(huán)境下等離子體實驗提供理論指導.
[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，
