Abstract

Abstract: The Hall effect, correction to Ohm’s law, on the energy decay of MHD turbulence is studied by using high-resolution numerical simulations, and the energy decay law with t^–1 exponent is derived for the case of small or zero magnetic helicity.

Key words: Turbulence, MHD turbulence, Energy decay, Hall effect, Numerical simulation

摘要： 通过数值模拟研究了欧姆定律中的Hall效应修正对MHD湍流的能量衰减的影响。在低或没有磁螺旋性约束的情况下推导出了

t^–1能量衰减律。

关键词: 湍流, MHD湍流, 能量衰减, Hall效应, 数值模拟
