摘要

Fluid/structure interaction (FSI) or otherwise known as Solid-stress, Fluid-flow and Thermal analysis (SFT) has importance in many engineering areas. Examples are found in diverse fields such as aeronautics, biomechanics and the offshore industries, and as such, Computational Fluid Dynamics (CFD) and Finite Element (FE) analysis techniques have evolved into this field. In the most general sense, the problem is tackled by either a Monolithical approach that integrates the fluid/structure interaction as a single system and solves simultaneously for the fluid and the structure, or, a Coupled Field approach that couples separate structural and fluid solvers tough various algorithms. There are advantages and disadvantages with each. This study focuses on the theory of a displacement based finite volume method that can be applied to the FSI (or SFT) problem. The approach is to be used as part of a CFD program and incorporated in a Monolithical manner.
