ABSTRACT
The present investigation applies fluid dynamics principles and numerical analysis techniques in an attempt to study stress distributions in blood caused by the motion of the occluder in a prosthetic heart valve. An interactive computer graphics program is developed for control of the computer simulation of the flow process and the pictoral presentation of the solution for analysis. A simplified model of a disc-type heart valve is used in the analysis to demonstrate the capability of the interactive graphics program. Resulting displays show the stress distribution and other useful information describing the movement of a disc occluder from almost full-closed position to almost full-open position. The possible contribution of this study to the understanding of hemolysis and thrombosis is discussed.
