The influence of self-generated magnetic fields on the Rayleigh-Taylor instability

R G Evans1986年Plasma Physics and Controlled FusionIF 2.2出版社

In the absence of magnetic diffusion the self-generated magnetic field in a plasma is proportional to the fluid vorticity. The ratio of magnetic to fluid energy then shows that self-generated magnetic fields can only affect the Rayleigh-Taylor growth rate for large k (wavelengths less than a few microns). Reduction of the plasma thermal conductivity on the other hand is more important for small k, i.e. long wavelength modes.

日本語訳

磁気拡散がない場合、プラズマ中の自己生成磁場は流体渦度に比例する。磁気エネルギーと流体エネルギーの比は、自己生成磁場がレイリー・テイラー成長率に影響を与えるのは大きなk(波長が数ミクロン未満)の場合のみであることを示している。一方、プラズマの熱伝導率の低減は、小さなk、すなわち長波長モードにとってより重要である。
