Title: Finite element simulation of blood flow in a carotid artery bifurcation
Issue Date: 2011
Abstract: The purpose of this paper is to present a numerical simulation system for aclinical study of the carotid artery bifurcation. The finite element method is used tosimulate blood flow in a complicated geometry. Blood flow is described by theincompressible Navier-Stokes equations and the simulation is carried out under unsteadyflow conditions. In diseased vessels which are often the subject of interest, the arteries areeven less compliant and wall motion is further reduced and the assumption of zero wallmotion is utilized in most approximations. Traction free outflow conditions are used assimulations of blood flow and pressure in arteries require outflow boundary conditions,witch have significant influence on velocity and pressure fields, especially in 3Dsimulations. In the present work, biochemical and mechanical interactions between bloodand vascular tissue are neglected. Hemodynamic of blood flow in the carotid bifurcationis considered under real flow conditions. Results from numerical modelling of blood flowthrough arteries using the developed finite element method are presented and validated.
