Mathematical model of pulsatile micropolar flow in tapered stenosed arteries extends simulation tools; leaves open clinical translation pending in vivo validation.
Mathematical modeling demonstrates that increasing the taper angle in an overlapping arterial stenosis increases axial velocity and volumetric flow rate while reducing resistive impedance.
Haghighi et al. (2015) studied Overlapping arterial stenosis. Vessel tapering was evaluated on Flow characteristics (axial velocity, volumetric flow rate, microrotational velocity, resistive impedance). In a mathematical model of micropolar fluid flow, increasing the taper angle increased axial velocity and volumetric flow rate while reducing microrotational velocity and resistive impedance.
