Key result
Numerical analysis of unsteady fluid flow through stenosed vessels showed that pressure gradient, impedance, and peak wall shear stress are increasingly sensitive to the degree of stenosis.
Computational modeling demonstrates that pressure gradient, impedance, and peak wall shear stress are highly sensitive to the degree of vessel stenosis.

May guide computational stenosis research; leaves open clinical translation pending human validation.
Kumar et al. (1998) studied Stenosed vessels. Degree of stenosis (0-75%) was evaluated on Velocity, pressure and stress fields. Numerical analysis of unsteady fluid flow through stenosed vessels showed that pressure gradient, impedance, and peak wall shear stress are increasingly sensitive to the degree of stenosis.
