Non-Newtonian blood flow in human right coronary arteries: steady state simulations.
TL;DR: It is concluded that, while the Newtonian model of blood viscosity is a good approximation in regions of mid-range to high shear, it is advisable to use the Generalised Power Law model in order to achieve better approximation of wall shear stress at low shear.
Journal ArticleDOI
The influence of the non-Newtonian properties of blood on the flow in large arteries: steady flow in a carotid bifurcation model.
TL;DR: In the computations, the shear thinning behavior of the analog blood fluid was incorporated through the Carreau-Yasuda model, and this seems to be the dominant non-Newtonian property of the blood analog fluid under steady flow conditions.

TL;DR: These data show for the first time in vivo that the Th variations in Wallstents at 6-month follow-up are inversely related to the relative SS distribution, which supports a hemodynamic mechanism underlying in-stent neointimal hyperplasia formation.
Journal ArticleDOI
An anatomically based model of transient coronary blood flow in the heart
TL;DR: An efficient finite difference model of blood flow through the coronary vessels is developed and applied to a geometric model of the largest six generations of the coronary arterial network by constraining the form of the velocity profile across the vessel radius.

The influence of the non-Newtonian properties of blood on the flow in large arteries: unsteady flow in a 90° curved tube
TL;DR: In this paper, a numerical and experimental investigation of unsteady entry flow in a 90 degrees curved tube is presented to study the impact of the non-Newtonian properties of blood on the velocity distribution.
