Numerical analysis of coronary artery flow

Abstract

The numerical analysis of coronary artery flow was presented. The importance of time-dependence of the flow pulse, motion of the arterial wall and non-Newtonian properties of blood for the wall shear stress and wall stress distribution was investigated. The analysis showed that characteristic shear rate was such that a viscosity based on infinite shear rate yields significantly different flow patterns and a large influence of wall motion and time-dependent curvature
