Abstract
A generic engineering example of fluid-structure interaction (FSI) is the motion
of thin-walled, leaflet-like structure driven by fluid motion. A standard example
in biomechanics is the opening and closing of aortic heart-valves, which is a delicate
interaction between blood flow and geometrical and stiffness properties of
the heart-valve leaflets. The coupled motion of flow and leaflet motion has been
achieved in only a limited number of cases. In this paper a feasibility study of the
dynamic mesh model in FLUENT is discussed for simulating heart valves during
the ejection (systole). This study resulted in a simplified n
