Interacting filamentary eruptions in magnetised plasmas

S A Henneberg, S C Cowley, H R Wilson2015年Plasma Physics and Controlled FusionIF 2.2出版社

The interaction between multiple filamentary plasma eruptions is investigated by modelling the non-linear ideal MHD ballooning mode envelope equation with a mixed Eulerian and Lagrangian characterisation of the boundary conditions. The study of multiple plasma filaments is performed in a specific slab equilibrium susceptible to Rayleigh–Taylor instabilities. If the unstable system is initiated with three equal sized filaments, they erupt at the same rate, independently of each other, even in the non-linear regime. However, if one is initiated very slightly larger than the other two it causes a down-draft as it erupts upwards, which suppresses the smaller filaments. This suggests that those filaments which first enter the non-linear regime will dominate the plasma eruption dynamics.

複数のフィラメント状プラズマ噴出の間の相互作用は、混合オイラー・ラグランジュ的境界条件の特性を用いた非線形理想MHDバルーニング包絡方程式のモデル化によって調査される。複数プラズマフィラメントの研究は、レイリー・テイラー不安定性を受けやすい特定のスラブ平衡状態において実施される。不安定な系が3つの等しいサイズのフィラメントで開始された場合、それらは非線形領域においても互いに独立して同じ速度で噴出する。しかしながら、1つのフィラメントが他の2つよりわずかに大きく開始された場合、それは上方へ噴出する際に下降気流を引き起こし、より小さいフィラメントを抑制する。このことは、最初に非線形領域に入るフィラメントがプラズマ噴出ダイナミクスを支配することを示唆している。
