Tearing Mode Instability And Magnetic Reconnection Driven By Boundary Perturbations

Magnetic reconnection is both regional phenomenon of astrophysics and very importantstudy subject in plasma physics of the solar system, also is general-existing basic physicalphenomenon in both space plasma and laboratory plasma. The phenomenon happens in themagnetospheric plasma, solar atmosphere, and cometic magnetosphere as well as fusionequipments. Nevertheless, the true process of magnetic connection needs to be researchedfurther. It is still not figured out that the connection between magnetic connection and solarsystem plasma. All above are the focuses among the solar physicists and space physicistsrecently.First of all, basic knowledge of space plasma physics and the general situation of ourcountry's spatial detection are introduced. Then, it introduces the basic conception andprocess of physics of magnetic connection, plasma instability and forced magnetic connectionwhich are for computation and introduction. It studies magnetic connection with MHD fluidequations and four order Runge-Kutta method, and gets the picture of magnetic field andvelocity of 2 dimension tearing mode instability, 2 dimension Inflow perturbation of cosinemagnetic connection, 2 dimension Inflow perturbation of including time magnetic connectionand Two dimensions three components tearing mode instability. It gets some useful resultswith MHD fluid method and classic mode and discovers some processes and phenomena ofphysics which is meaningful to the research of magnetic connection.
