Abstract:
We have tried to simulate the aortic valve behavior with a particle method. The simulation model has been
generated from CT data; however, the model was a little bit distorted due to some diseases. The distorted
model is not appropriate for the simulation because we have to simulate the aortic valve behavior for various
kinds of conditions. Then, we have created the normal model by modifying the generated model. In order to
simulate the aortic valve behavior, blood should be flown in the aortic model and particle methods are suitable
for fluid simulation. On the other hand, FEM (Finite Element Method) is usually used for the simulation
of elastic body such as the aortic wall and the aortic valve. However, it is difficult to calculate the mutual
interaction between fluid and elastic body if two different kinds of methods such as particle method and FEM
are adopted for one simulation. Therefore, we have applied a particle method for both of fluid and elastic
body. As the result of the
simulation, we have been able to visualize the blood flow and the pressure inside the
aorta, and the stress distribution on the aortic valve.
