Abstract
A simulation would be a very effective method for analysis associated with a prosthetic heart valve. In this paper we developed a simulation program with the finite difference method for fluid analysis under st eady flow condition. The numerical fluid analysis that obtained by thi s analysis program was consistent with the results of flow visualizati on experiment. By combining the Euler method and the Lagrange method s imulated flow visualization of imaged particles is possible. This is e ffective for an understanding of flow dynamics around prosthetic heart valves.
