TLDR
The measured velocities showed that blood flow keeps a parabolic sectional profile distal from CCA, ECA and ICA, while being quite disturbed in the carotid sinus with a significant decrease in magnitude making this site very prone to atherosclerosis.About:

Spatio-temporal evolution of magnetohydrodynamic blood flow and heat dynamics through a porous medium in a wavy-walled artery.
TL;DR: In this paper, a wavy-walled arterial structure is simulated by applying a vorticity-stream function formulation approach. And the transformed dimensionless equations are further discretized using the finite difference method by developing the Peaceman-Rachford alternating direction implicit (P-R ADI) scheme.

A computational model for cardiovascular hemodynamics and protein transport phenomena
TL;DR: In this article, the authors proposed a largeeddy simulation (LES) approach to carry out the hemodynamics and medication dispersion and deposition studies inside the descending aorta. And the analysis reveals that the flow separation causes a preferential deposition and build-up of low-density lipoproteins (LDL) on the arterial surface.

TL;DR: The MRI‐based techniques that were used in the current study for measuring arterial flow in pediatric and adolescent patients demonstrated acceptable test‐retest reliability both at rest and immediately post‐exercise.

Comparative study of Newtonian physiological blood flow through normal and stenosed carotid artery
TL;DR: In this paper, a numerical simulation is performed to investigate Newtonian physiological flows behavior on three dimensional idealized carotid artery (CA) and single stenosed (75% by area) carotis artery(SCA).

Effect of Surface Re-Meshing on Hemodynamic Simulations Quality in Carotid Arteries
Asma Ben Abdallah,Arij Debbich +1 more
TL;DR: An approach to quantify the effect of surface re-meshing on hemodynamic modeling by evaluating the Eucledean similarity, rate of change and RMSE between the measured and modeled velocity obtained with different mesh densities.
