It is well known that the fluid dynamics of arterial blood flow plays an important role in arterial disease. Periodic blood flow through a stenosed tube was analyzed numerically. The bi-viscosity model is used as a constitutive equation for blood, and the flow is assumed to be periodic, incompressible and axisymmetric. Effects of pulsation and the rheological property of blood are considered. The flow pattern, separation region and the distributions of pressure and shear stress at the wall are obtained. The results show that the non-Newtonian property reduces the strength of vortex downstream of the stenosis and has considerable influence on the flow even at high Stokes and Reynolds numbers, provided the pulsatile flow has a stagnant period.
