In this study characteristics of steady and pulsatile flows of Newtonian and non-Newtonian fluids in the stenosed circular tubes are investigated by finite element method. Present analysis discusses the effects of stenosed geometry and the stenosis spacing and the number of stenosis in the periodically stenosed tubes on the pulsatile flow. Velocity in the central region during the acceleration period is much flatter than that during the deceleration period of pulsatile flow. Flow recirculations occur in the wall region for the steady flow and during deceleration period of the pulsatile flow. As the number of stenosed section increases for the pulsatile flow the total pressure change increases even though the velocity fields around the stenoses are very similar. When the length of stenosis spacing is changed for the pulsatile flow the difference between the local maximum and minimum values of the velocity is almost negligible during the acceleration period but very large during the deceleration period.
