Key result
Magnetic fields control carotid flow patterns in a computational model, suggesting potential utility in hypertension.
Why the study?
The effects of magnetic fields on arterial blood flow through the carotid artery and fluid–wall interactions require investigation to understand potential flow control applications.
Does the application of a magnetic field affect blood flow patterns in a computational model of the carotid artery?
Does the application of a magnetic field affect blood flow patterns in a computational model of the carotid artery?
A computational finite element model demonstrates that magnetic fields can control blood flow in the carotid artery, suggesting potential future applications in conditions like hypertension.
No immediate clinical role in hypertension; leaves open whether magnetic flow modeling merits in vivo translation.
The present paper a finite element implementation of a model of the arterial blood flow through the carotid artery with the effects of magnetic to considering fluid–wall interactions are investigated. The Navier–Stokes equations are used as the governing equations for the blood flow while an elastic compliant model is used for the arterial wall. The reduced one dimensional model solves the momentum and continuity equations in compliant tubes so as to reproduce the propagation of the pressure pulse in the arterial model. The obtained results adequately reproduce the general flow patterns reported in the literature. The results obtained in the investigation are in reasonably good agreement with experimental findings existing in the literature. The effects of a magnetic field have been used to control the flow, which may be useful in certain hypertension cases, etc.

A 2011 study studied Arterial blood flow / Hypertension. Magnetic field application (computational model) was evaluated on Blood flow patterns and pressure pulse propagation. A finite element model of carotid artery blood flow demonstrated that magnetic fields can control flow patterns, suggesting potential utility in managing certain hypertension cases.
