ABSTRAKT

Numerical solving of fluid-structure interaction (FSI) problems are of importance in various scientific fields. In particular, the establishment of stable numerical scheme is needed in order to analyze the details of flow phenomena. In the present paper, we propose a weak-coupling method for FSI problem: for a elastic body the rigorous equations of motion are discretized with finite volume method; in the flow computation, the elastic body object is reproduced via immersed boundary method. To demonstrate the performance of proposed scheme, the 3D structure analysis and 3D FSI problems of a elastic body are solved. The results indicate that the computation is stably conducted using the proposed method, in spite of the occurrence of fairly large deformation of the object. In addition it turns out that the realistic flow including turbulence phenomena is well reproduce using the proposed FSI scheme.
