dc.description.abstractSteady-state boundary layer flow generated on a rotating fluid-saturated porous bed when a column of axisymmetric frictionless potential flow arriving from infinity impinges on it is studied numerically by employing an appropriate boundary condition to account for the presence of tarIgential slip in the radial and transverse directions on the permeable interface which separates the boundary layer from the Darcy flow occurring in the porous bed. Two important physical parameters which influence the dynamic coupling between these two flows are rotation and permeability of the porous bed. An interesting result of this study is that to each value of rotation parameter s, there corresponds a permeability value Ko for which the velocity component normal to the bed and the radial shear stress vanish at every point on the bed; that is, under certain conditions the radial shear stress can be completely annihilated and the porous bed made to behave as if it were an impermeable plane.en
