FLUID-STRUCTUER INTERACTION ANALYSIS BASED ON FINITE COVER METHOD USING SHALLOW WATER EQUATION

Abstract

This paper presents a numerical method for Fluid-Structure analysis based on Finite Cover Method using shallow water flow. With the help of the two-dimensional finite cover method (FCM) as a tool for interface capturing, the effect of debris is taken into account in fluid-structure interaction (FSI) analyses with the standard shallow water equation. The discontinuous interface boundary between the debris and the fluid is expressed by the Finite Cover Method. The motion of the debris is analyzed by Discrete Element Method (DEM) and the rigid body motion is calculated by using the fluid force action on the debris. For the fundamental resarch, several numerical examples are presented to demonstrate for the proposed fluid-structure interaction method.
