Abstract: The steady flow of Jeffrey fluid through a tube with both constrictions and dilatations have been studied. The expressions for velocity, pressure drop, volumetric flow rate, resistance to the flow, wall shear stress have been derived by assuming that the stenosis is mild. It is found that the resistance to the flow increases with the height of the stenosis and decreases with post stenotic dilatation. The pressure drop, velocity and shear stress at the walls decrease with the height of stenosis and Jeffrey fluid parameter, but the same parameters increase with the post stenotic dilatation

Keywords: Jeffrey fluid, stenosis, dilatation, Jeffrey fluid parameter, wall shear stress.
