Current-vortex filaments in magnetized plasmas

J Bergmans, B N Kuvshinov, V P Lakhin, T J Schep, E Westerhof1999年Plasma Physics and Controlled FusionIF 2.2出版社

Current-vortex filament solutions to the two-fluid plasma equations that describe drift-Alfvén waves are presented. Such filament systems are Hamiltonian. Integrable three and four filament systems are discussed in some detail. A wide variety of orbit topologies exists in the plasma case. Special attention is paid to collapses where all filaments contract to a single point. The differences and extensions with respect to point vortex solutions in two-dimensional (2D) incompressible Euler systems is pointed out.

電流渦糸解は、ドリフト・アルヴェン波を記述する二流体プラズマ方程式に対して提示される。このような渦糸系はハミルトニアン系である。可積分な三渦糸系および四渦糸系について、いくつかの詳細な考察が行われる。プラズマの場合には、多様な軌道トポロジーが存在する。すべての渦糸が単一の点に収縮する崩壊に特に注目が払われる。二次元(2D)非圧縮オイラー系における点渦解との相違点および拡張点が指摘される。
