弁の開閉を考慮した大動脈血流の渦構造と周期性に関する研究

抄録

The objective of this research is to asses the periodicity in pulsating-arterial-flow with non-uniform rational B-spline (NURBS) representation of aorta. We compare wall shear stress (WSS) and the second invariant of the velocity gradient tensor to evaluate the periodicity. We also compute flow with aortic valve, and show the impact in the aortic arch due to the leaflets motion.
