Time-Dependent MHD Couette Flow of a Rotating Fluid With Hall and Ion-Slip Currents

  • 摘要: 考虑Hall和离子滑移电流的影响,在旋转系统中研究导电流体非稳定的MHD Couette流动.在小数值磁场Reynolds数假定下,推导出基本的控制方程,使用著名的Laplace变换技术,数值地求解该基本方程.分两种情况:磁场相对于流体或者移动平板固定时,得到速度和表面摩擦力统一的闭式表达式.用图形讨论了问题的不同参数,对速度和表面摩擦力的影响.所得结果显示,主流速度u和次生速度v随着Hall电流而增大.离子滑移电流的增大,也会导致主流速度u的增大,但会使次生速度v减小.还给出了旋转、Hall和离子滑移参数的综合影响,确定了次生运动对流体流动的贡献.
