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: In this paper , simultaneous effects of tDCS on cerebral blood flow (CBF), venous blood oxygenation (Yv) and cerebral metabolic rate of oxygen (CMRO2) using simultaneous MRI in healthy adults to provide a reference frame for its neurobiological mechanisms.

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.

TL;DR: The results illustrate the feasibility of using 3-D US for precise and angle-independent volume flow and PSV estimation in vivo and validate a recently proposed technique for 3- D US vector flow imaging.

TL;DR: This study suggests that OCT-based FSI model may be useful for plaque vulnerability assessment and it may be critical to perform the FSI simulation if an accurate WSS value is required.

Evidence for non-Newtonian behavior of intracranial blood flow from Doppler ultrasonography measurements
TL;DR: Evidence suggests that the Newtonian assumption may be inappropriate to investigate intracranial hemodynamics and could affect the physical interpretation of IA CFD studies.

Boundary control in computational haemodynamics
TL;DR: In this paper, a data assimilation method is proposed following an optimise-then-discretise approach, and is applied in the context of computational haemodynamics, which remarkably improves the flow field at the aortic root and reveals a great potential for predicting clinically relevant haemodynamic phenomenology.

On Recent Progress in Modelling and Simulations of Multi-scale Transfer of Mass, Momentum and Particles in Bio-medical Applications
TL;DR: It is demonstrated that a recently developed mathematical model, which takes into account the complex multi-layer arterial-wall structure, produced LDL profiles within the artery wall in good agreement with in-vivo experiments in rabbits, and it can be used for predictions of locations where the initial stage of development of atherosclerosis may take place.
