Journal ArticleDOI
Three-dimensional numerical analysis of pulsatile flow and wall shear stress in the carotid artery bifurcation
TL;DR: Numerical results are presented for axial and secondary flow velocity and wall shear stresses with special emphasis on the fluid dynamics in the carotid sinus, of major interest because it is affected preferentially by lesions.

Atherosclerosis at arterial bifurcations: evidence for the role of haemodynamics and geometry
Umberto Morbiducci,Annette M. Kok,Brenda R. Kwak,Peter Stone,David A. Steinman,Jolanda J. Wentzel +5 more
TL;DR: This review focuses on carotid and coronary bifurcations because of their primary relevance to stroke and heart attack and highlights reported relationships between atherosclerotic plaque location, progression and composition, and fluid forces at vessel's wall.
Journal ArticleDOI
Flow Imaging and Computing: Large Artery Hemodynamics
TL;DR: Progress within the last decade in terms of the technical development and application of flow imaging and computing is summarized, rather than the knowledge derived from specific studies.
Journal ArticleDOI
A computer simulation of the non-newtonian blood flow at the aortic bifurcation
Zheng Lou,Wen-Jei Yang +1 more
TL;DR: A two-dimensional numerical model was developed and it was disclosed that the non-Newtonian property of blood did not drastically change the flow patterns, but caused an appreciable increase in the shear stresses and a slightly higher resistance to both flow separations and the phase shifts between flow layers.

Numerical modeling of simulated blood flow in idealized composite arterial coronary grafts : Steady state simulations
Argyris Politis,G.P. Stavropoulos,M.N. Christolis,F.G. Panagopoulos,Nicholas S. Vlachos,N.C. Markatos +5 more
TL;DR: It was concluded that local haemodynamics, practically described by velocity, pressure drop, wall shear stress (WSS) and flow rates, may be strongly influenced by the local geometry, especially at the anastomotic sites.

Finite Element Methods for Navier-Stokes Equations: Theory and Algorithms
TL;DR: This paper presents the results of an analysis of the "Stream Function-Vorticity-Pressure" Method for the Stokes Problem in Two Dimensions and its applications to Mixed Approximation and Homogeneous Stokes Equations.

Navier-Stokes Equations
TL;DR: Schiff's base dichloroacetamides having the formula OR2 PARALLEL HCCl2-C-N ANGLE R1 in which R1 is selected from the group consisting of alkenyl, alkyl, alkynyl and alkoxyalkyl; and R2 is selected by selecting R2 from the groups consisting of lower alkylimino, cyclohexenyl-1 and lower alkynyl substituted cycloenenyl -1 as discussed by the authors.
Journal ArticleDOI
Atheroma and arterial wall shear. Observation, correlation and proposal of a shear dependent mass transfer mechanism for atherogenesis.
TL;DR: It appears that wall shear rate may be a major controlling factor in the development of atheromatous lesions in man and in animals and a net flux of cholesterol from blood to wall cannot account for the observed normally occurring (quasi-steady state) and experimentally induced atheroma.
Journal ArticleDOI
Acute Vascular Endothelial Changes Associated with Increased Blood Velocity Gradients
TL;DR: The purpose of this study is to quantify the acute changes in endothelial histology that are associated with an induced increase in blood velocity and to establish the “normal” endothelial cell population density as a function of stress exposure.

Pulsatile flow of non-Newtonian fluid in distensible models of human arteries.
D. Liepsch,St. Moravec +1 more
TL;DR: Emphasis is placed on the difference between rigid and elastic models and also Newtonian and non Newtonian flow behavior after branches where the flow has local strong convective elements such as in reverse zones and flow separation points.
