| description | The objective of this paper is to present the mixed velocity-pressure (v-p) finite element
method that solves the pulsatile blood flow in arteries. The solution exploits the Galerkin
method and the fully implicit incremental-iterative procedure for the three-dimensional
nonlinear finite element equations. This methodology is applied to model biological flows
that are important in predicting growth and rupture risks in abdominal aortic aneurysms
(AAA). The numerical technique was validated with the analytical solution of the
Womersley model. Next, a physiologically realistic pulsatile blood flow waveform was
imposed onto the idealized cylindrical arterial model and solved as a benchmark problem.
The model represents a healthy abdominal aorta.This pulsatile condition simulates an in
vivo aorta at rest. The numerical results were used to quantify clinically relevant flow
dynamics that play a significant role in today’s field of medical treatment planning and
development of predictive methods via computational modelling for assessing common
clinical problems such as AAAs. (Authors' abstract) |
