Abstract

Feasibility study of the dynamic mesh model in FLUENT for fluid-structure interaction of a heart valve K. ~umontl, J. vierendeels2, P.R. verdonckl 'IBITECH, Institute of Biomedical Technology, Hydraulics Laboratory, Ghent University, Gent, Belgium ' ~ e ~ a r t m e n t of Flow, Heat and Combustion Mechanics, Fluid Mechanics Laboratory, Ghent University, Gent, Belgium 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
