The upstream boundary condition influences the leaflet opening dynamics in the numerical FSI simulation of an aortic BMHV

Autor: Pascal Verdonck, Joris Degroote, Jan Vierendeels, Tom Claessens, Patrick Segers, Sebastiaan Annerel

Publikováno v: International Journal for Numerical Methods in Biomedical Engineering. 28:745-760

In this paper, the influence of the upstream boundary condition in the numerical simulation of an aortic bileaflet mechanical heart valve (BMHV) is studied. Three three-dimensional cases with different upstream boundary conditions are compared. The f

In this article, we present a fluid-structure interaction algorithm accounting for the mutual interaction between two rigid bodies. The algorithm was used to perform a numerical simulation of mitral valve (MV) dynamics during diastolic filling. In nu

Currently, the interaction between free surface flow and an elastic structure is simulated with monolithic codes which calculate the deformation of the structure and the liquid–gas flow simultaneously. In this work, this interaction is calculated i

Publikováno v: Annals of biomedical engineering. 43(6)

The aim of this study was to reconcile some of our own previous work and the work of others to generate a physiologically realistic numerical simulation environment that allows to virtually assess the performance of BMHVs. The model incorporates: (i)

Validation of a numerical FSI simulation of an aortic BMHV by in vitro PIV experiments

Autor: Tom Claessens, Joris Degroote, Sebastiaan Annerel, Patrick Segers, Jan Vierendeels

Publikováno v: Medical engineeringphysics. 36(8)

In this paper, a validation of a recently developed fluid-structure interaction (FSI) coupling algorithm to simulate numerically the dynamics of an aortic bileaflet mechanical heart valve (BMHV) is performed. This validation is done by comparing the

One of the major challenges in the design of Bileaflet Mechanical Heart Valves (BMHVs) is reduction of the blood damage generated by non-physiological blood flow. Numerical simulations provide relevant insights into the (fluid) dynamics of the BMHV a

In previous work of the authors, Fourier stability analyses have been performed of Gauss-Seidel iterations between the flow solver and the structural solver in a partitioned fluid-structure interaction simulation. These analyses of the flow in an ela

Aortic Valve

Since the first clinical implantation of an artificial aortic valve by Dr. Charles A. Hufnagel in 1952 (Hufnagel et al., 1954), the use of such prostheses has gained strong interest and has become a routine treatment for severe heart valve failure. D
