运用并扩展了Guzdar等人提出的一种简单的低维模型,讨论了交换模湍流中的非线性逆磁效应对带状流产生的影响,通过对非线性演化方程的数值计算,得到如下结论:逆磁效应能抑制通常的(雷诺胁强驱动的)极化非线性效应,由此导致带状流的阻尼.
A simple low-dimensional model proposed by Guzdar et al. Is used and extended. The influence of nonlinear inverse magnetic effect on the banded flow in the exchange-mode turbulence is discussed. The numerical results of the nonlinear evolution equation are given as follows : The inverse magnetic effect can suppress the usual (non-Reynolds-driven) polarization nonlinear effect, thereby resulting in the damping of the ribbon flow.
