摘要

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 slipparameter 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, incom pressible and Newtonian. Analytical so lutions were constructed for the governing equations using Beavers-Joseph slip boundary conditions. Effects of the magnetic field, permeability, Darcy velocity and slipparameter on the axial velocity, slipvelocity and shear stress were discussed in detail. It is seen that the Hartmann number, Darcyvelocity, porous parameter and slipparameter play avital role in altering the flow and in turn the shear stress.
