Large eddy simulation of a stenosed artery

Tracie Barber, A. Simmons

Abstract


A large eddy simulation is conducted of a 50% stenosed artery. The inlet boundary condition is a physiologically accurate pulsatile flow, representative of that found in a femoral artery. The transient, three dimensional results show the non-axisymmetric nature of the flow field; high values of wall shear stress, oscillatory in both space and time are also observed. The identification of such fluid dynamic quantities within a stenosed vessel is important in understanding the likely causes and ongoing effects on the integrity of the vessel.
