Fig. 3.

Normalized axial centerline instantaneous velocity during the last cycle for three degrees of stenoses and three oscillation frequencies in the axisymmetric and the eccentric cases at Re $=$ 2000. For oscillation frequencies, ${\omega }_1$ and ${\omega }_2$ last two and four cycles are shown. The black, green and red lines respectively correspond to $60\%$, $50\%$ and $25\%$ stenosis degrees
