    Abstract
  • Magnetic reconnection is one of the hot topics in space physics. The magnetic Lundquist number can influence the magnetic reconnection process drastically. Magnetic Lundquist number is always very large in many real physical environments, for example, higher than 104 in interplanetary space and solar corona. Magnetic reconnection with enormously large Lundquist number behaves many new characteristics, while magnetic reconnection simulation needs very high grid resolution, or it can't resolve the thin current sheets formed in the magnetic reconnection. With the help of the Adaptive Mesh Refinement (AMR) package named PARAMESH, AMR technique was introduced into magnetic reconnection simulations and a two and half dimensional (2.5D) AMR magnetic reconnection model was developed. The dynamic reconnection process with different magnetic Lundquist numbers was studied. The results showed that this model can automatically capture the near-singular current sheets with the development of the magnetic reconnection and the slow-mode shock structures formed in the magnetic reconnection process with high magnetic Lundquist number provide a possible way for fast magnetic energy conversion.
