摘要:

模拟在推动我们对磁重联的认识方面发挥了关键作用。然而,由于磁重联固有的多尺度特性,不可能在所有尺度上模拟所有物理过程。因此,人们设计了各种各样的模拟方法来研究磁重联的特定方面和后果。本章回顾了其中许多方法,阐述了关键假设、数值技术,并给出了科学结果的示例。所描述的等离子体模型包括磁流体力学(MHD)、霍尔磁流体力学(Hall MHD)、混合模型、动理学粒子云网格(PIC)方法、动理学 Vlasov 方法、内嵌 PIC 的流体模型、具有高能粒子群直接反馈的流体模型,以及 Rice 对流模型(RCM)。

英文摘要:

Simulations have played a critical role in the advancement of our knowledge of magnetic reconnection. However, due to the inherently multiscale nature of reconnection, it is impossible to simulate all physics at all scales. For this reason, a wide range of simulation methods have been crafted to study particular aspects and consequences of magnetic reconnection. This chapter reviews many of these methods, laying out critical assumptions, numerical techniques, and giving examples of scientific results. Plasma models described include magnetohydrodynamics (MHD), Hall MHD, Hybrid, kinetic particle-in-cell (PIC), kinetic Vlasov, Fluid models with embedded PIC, Fluid models with direct feedback from energetic populations, and the Rice Convection Model (RCM).
