Flow patterns in the human carotid artery bifurcation.
To elucidate the connection between blood flow and the localized genesis and development of atherosclerosis and thrombosis at the human carotid artery bifurcation, detailed studies of the flow patterns and distributions of fluid velocity and wall shear rate in this region were carried out using a transparent segment of the carotid artery, prepared from a human subject postmortem, and cinemicrog...
متن کاملPulsatile Blood Flow in Human Carotid Bifurcation
The purpose of this paper is to present a numerical simulation system for blood flow in the carotid artery bifurcation and its validation using experimental data collected in clinical practice. Blood flow is described by the incompressible Navier-Stokes equations and the simulation is carried out under pulsatile conditions using inlet velocities given by a flow wave form obtained by ultrasound ...
متن کاملParametric geometry exploration of the human carotid artery bifurcation.
A parametric computational model of the human carotid artery bifurcation is employed to demonstrate that it is only necessary to simulate approximately one-half of a single heart pulse when performing a global exploration of the relationships between shear stress and changes in geometry. Using design of experiments and surface fitting techniques, a landscape is generated that graphically depict...
متن کاملNumerical analysis of 3D blood flow and common carotid artery hemodynamics in the carotid artery bifurcation with stenosis.
The results for blood flow in the carotid artery bifurcation on the basis of numerical simulation of Navier-Stokes equations are presented in this study. Four cases of carotid bifurcation are considered: common carotid artery (CCA) bifurcation without stenoses and cases with one, two and three stenoses are also presented. The results are obtained by performing numerical simulations considering ...
متن کاملPulsatile flow in a model carotid bifurcation.
Pulsatile flow in an in vitro model of the human carotid bifurcation was studied by flow visualization using hydrogen bubble techniques. A glass model was constructed after determining an average geometry from 57 biplanar angiograms of 22 subjects ranging from 34 to 77 years of age. The flow pulse used was a half-sine wave superimposed upon a mean flow. Maximum and minimum values of the instant...
