Research of turbulent magnetic reconnection using high-resolution MHD simulations

本研究的目的是利用直接磁流体动力学（MHD）模拟研究高磁雷诺数下的湍流磁场重联。因此，为了长期进行高精度的MHD数值模拟，人们开发了全新的MHD数值计算技术。这些数值计算技术使我们能够探索有史以来最高的磁雷诺数之一的电阻磁重联。作为模拟的结果，发现了重联率的快速增加与次级等离子体团的反弹运动之间的相关性

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
