Abstract: Approximately two-thirds of heart valves are The thin wing theory of aircraft aerodynamics
bileaf plane mechanical heart valves, however the plane [1]
valveleaf is not the best shape for the hydrodynamic was applied to heart valve design . According this
characteristics. The main purpose of this study is to theory, the bileaf wing heart valve has been designed
compare the hydrodynamic characteristics of plane
and owned much better properties of the hydrodynamic
valve with curved valve under the steady flow analysis.
In this work, two styles of curved valves were designed behavior. It does not only decrease the volume of back
and nine different 3D flow models were constructed. All flowing, but also improve performance of the valve
of the simulations were carried out by using
ANSYS/Flotran software. The result shows that the closure.
flowing volumes through the curved valves are larger With the development putational
