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.
