Abstract: Pulsatile flow patterns in rigid arterial models with stenosis (area constrictions) of 50% and 80% have been studied using the Finite Element Methods. Flow patterns of the constricted region have been investigated for a simulated physiological condition with an average Reynolds number of 561.8 and a Womersley number of 7.16. Velocity waveforms, axial pressure drop and wall shear stress distributions have been computed for each model and presented at several time steps. Flow separation zone near the stenosis...
