Abstract

We have proposed an Eulerian mesh-based scheme using the level set function to analyze large-deformation fluid-structure interaction (FSI) problems. In this scheme, we introduce an interface treatment technique using virtual particles with the level sets and structural velocity components in order to enforce the kinematic condition at the interface on a fluid fixed mesh. In this study, we address problems where the boundary layer is relatively thin, such as coupled problems of external flow and a submerged elastic structure, for which it is necessary to consider adaptive mesh refinement (AMR) near the fluid-structure interface. We show the algebraic performance and numerical results compared with the ALE (Arbitrary Lagrangian-Eulerian) mesh-based scheme.
