3D Dissipation Mechanism in Fast Magnetic Reconnection
Magnetic reconnection is a promising process which provides efficient energy release in solar flares and geomagnetospheric substorms. The process is also considered be important in fusion devices because it can disturb the plasma confinement due to the magnetic field. The efficient energy release of the magnetic field requires a locally intense electric resistivity. However, the generation mech...
متن کاملThe Role of Helicity in Magnetic Reconnection: 3D Numerical Simulations
We demonstrate that conservation of global helicity plays only a minor role in determining the nature and consequences of magnetic reconnection in the solar atmosphere. First, we show that observations of the solar coronal magnetic field are in direct conflict with Taylor’s theory. Next, we present results from three-dimensional MHD simulations of the shearing of bipolar and multi-polar coronal...
متن کاملMagnetic reconnection
The fundamental physics of magnetic reconnection in laboratory and space plasmas is reviewed by discussing results from theory, numerical simulations, observations from space satellites, and recent results from laboratory plasma experiments. After a brief review of the well-known early work, representative recent experimental and theoretical works are discussed and the essence of significant mo...
متن کاملThree-Dimensional Magnetic Reconnection
The importance of magnetic reconnection as an energy release mechanism in many solar, stellar, magnetospheric and astrophysical phenomena has long been recognised. Reconnection is the only mechanism by which magnetic fields can globally restructure, enabling them to access a lower energy state. Over the past decade, there have been some major advances in our understanding of threedimensional re...
متن کاملExplosive turbulent magnetic reconnection.
We report simulation results for turbulent magnetic reconnection obtained using a newly developed Reynolds-averaged magnetohydrodynamics model. We find that the initial Harris current sheet develops in three ways, depending on the strength of turbulence: laminar reconnection, turbulent reconnection, and turbulent diffusion. The turbulent reconnection explosively converts the magnetic field ener...
