摘要

本文研究了在外加横向磁场作用下，小边界扰动对矩形管道中导电流体层流运动的影响。在管道的横截面上施加一个大小为0的边界微扰。利用对0的渐近分析，导出了速度和感应磁场的显式模型。数值结果证实了所考虑的扰动对渐近解有非局部影响。

Effects of small boundary perturbation on the MHD duct flow

In this paper, we investigate the effects of small boundary perturbation on the laminar motion of a conducting fluid in a rectangular duct under applied transverse magnetic field. A small boundary perturbation of magnitude ǫ is applied on cross-section of the duct. Using the asymptotic analysis with respect to ǫ, we derive the effective model given by the explicit formulae for the velocity and induced magnetic field. Numerical results are provided confirming that the considered perturbation has nonlocal impact on the asymptotic solution.
