霍尔磁流体力学中的帕克问题

Parker Problem in Hall Magnetohydrodynamics

Bhimsen K. Shivamoggi

摘要:

研究了霍尔磁流体力学(MHD)中的帕克问题。将极向剪切引入由霍尔效应产生的环形流中。发现这导致了Hall MHD中Parker问题的{ \it三层}结构,在中间霍尔电阻区(如\normalfont $1/x^3$)的磁场下降比在外部理想MHD区(如\normalfont $1/x$)的磁场下降更陡。

英文摘要:

Parker problem in Hall magnetohydrodynamics (MHD) is considered. Poloidal shear into the toroidal flow generated by the Hall effect is incorporated. This is found to lead to a {\it triple deck} structure for the Parker problem in Hall MHD, with the magnetic field falling off in the intermediate Hall-resistive region more steeply (like \normalfont $1/x^3$) than that (like \normalfont$1/x$) in the outer ideal MHD region.
