Research of turbulent magnetic reconnection using high-resolution MHD simulations

本研究的目的是通过直接磁流体动力学（MHD）模拟来研究高磁雷诺数下的湍流磁重联。因此，长期以来，为了实现高精度的MHD模拟，开发了全新的MHD数值技术。这些数值技术使我们能够在有史以来最高的磁雷诺数之一下探索电阻性磁重联。模拟结果表明，重联速率的快速增加与二次等离子体的弹跳运动之间存在相关性

The objective of this research is to study turbulent magnetic reconnection at high magnetic Reynolds numbers by using a direct magnetohydrodynamic(MHD) simulation. Therefore, brand new numerical techniques for MHD had been developed in order to perform highly accurate MHD simulations for a long time. These numerical techniques have enabled us to explore resistive magnetic reconnection at one of the highest magnetic Reynolds numbers ever. As a result of the simulations, a correlation was found out between the rapid increase of the reconnection rate and the bounce motion of a secondary plasmoid
