| 摘 要： | 研究等宽管道中,磁场、可渗透壁面、Darcy速度和滑动参数,对流体稳定流动的综合影响.假设管道中流动的流体是均匀的、不可压缩的Newton流体.利用Beavers-Joseph滑动边界条件,得到控制方程的解析解.详细地讨论了磁场、可渗透性、Darcy速度和滑动参数对轴向速度、滑动速度和剪应力的影响.可以看出,Hartmann数、Darcy速度、多孔参数和滑动参数,在改变流动方向,进而改变剪应力方面,起着至关重要的作用.

| Abstract: | The combined effects of magnetic field,permeable walls,Darcy velocity and slip parameter on the steady flow of a fluid in a channel of uniform width were studied.The fluid flowing in the channel was assumed to be homogeneous,incompressible and Newtonian.Analytical solutions were constructed for the governing equations using Beavers-Joseph slip boundary conditions.Effects of the magnetic field,permeability,Darcy velocity and slip parameter on the axial velocity,slip velocity and shear stress were discussed i... |
