This work focuses on the direct numerical simulation of the pulsatile flow through a bileaflet
mechanical heart valve under physiological conditions and in a realistic aortic root …

The complex fluid‐structure interaction problem associated with the flow of blood through a
heart valve with flexible leaflets is investigated both experimentally and numerically. In the …

The flow through a bileaflet mechanical heart valve during the first half of systole was
predicted using computational fluid dynamics (CFD). A three-dimensional model of the …

The effect of leaflet opening angle on flow through a bileaflet mechanical heart valve has
been investigated using computational fluid dynamics (CFD). Steady state, laminar flow for a …

Thromboembolic complications of bileaflet mechanical heart valves (BMHV) are believed to
be due to detrimental stresses imposed on blood elements by the hinge flows …

The immersed boundary (IB) method is a mathematical and numerical framework for
problems of fluid–structure interaction, treating the particular case in which an elastic …

Methods: A simple and effective method to track the moving boundary was proposed, and an
efficient method for calculating the blood-leaflet interaction applied. In this way, a CFD code …

Numerical analysis of the aortic valve has mainly been focused on the closing behaviour
during the diastolic phase rather than the kinematic opening and closing behaviour during …

We present comprehensive particle image velocimetry measurements and direct numerical
simulation (DNS) of physiological, pulsatile flow through a clinical quality bileaflet …

We have performed high-resolution fluid–structure interaction simulations of physiologic
pulsatile flow through a bi-leaflet mechanical heart valve (BMHV) in an anatomically realistic …
