摘要

研究了矩形截面倾斜通道间的非定常层状不可压缩导电微极流体问题。假设流动受到横向磁场的影响,通道壁面温度恒定,电导率有限。得到了不同参数条件下的速度场、磁场剖面、微旋场和温度场的数值解。这些结果用图形说明了控制流动的物理参数的影响。研究发现,速度、磁场分布和微旋度对流体的运动有促进作用,而壁面电导的增大对流体的运动有促进作用。速度和磁场随磁参量的增大而减小。

MHD Flow and Heat Transfer in a Moving Conducting Inclined Channel
The problem of unsteady laminar, incompressible, electrically conducting micropolar fluid between inclined channel of rectangular cross-section was studied. It is assumed the flow is under the influence of transverse magnetic field and   the walls of the channel have constant temperatures and finite conductivity. The numerical solutions was obtained for the velocity, magnetic field profile, microrotation and temperature fields for various parametric conditions. These results are illustrated graphically to illustrate the effects of the physical parameters governing the flow. It is found that velocity, magnetic field profile and microrotations promote the motion of the fluid with increase the with wall conductance. It is also found that both velocity and magnetic field decreases with magnetic parameter increases.
