Basic Research for Coupling Analysis Method of Free Surface Flow Based on Interface-Capturing Method and Structure

Abstract

This paper presents a coupling method of FEM for free surface flow and structure. This method is required for development of numerical analysis system in evaluating structural damage caused by debris collision. Debris is assumed to be a simple-shaped rigid body, and the calculation process of interaction between fluid FEM and rigid body is described in this paper. Furthermore, the numerical results are validated by comparing with an experimental result.
