Skewedness as a Signature of Dean Flow Measured by Echo-PIV
2022 IEEE International Ultrasonics Symposium (IUS), 2022 Studying secondary flow in the vascular system is of importance, as it is related to hemodynamic parameters such as wall shear stress. Moreover, newly designed helical stents for the superficial femoral artery could induce secondary or swirling flow inside the blood and characterizing this flow is of interest.
