Numerical Simulation for Motions of Two-dimensional Elastic Deformable Body in Fluid

Abstract

This paper describes a numerical method for simulating fluid-structure interaction, especially two-dimensional fluid-elastic body interaction problems. A model is formulated for the elastic shell made of thin film. Numerical simulations of the incompressible unsteady flow around the moving and deforming elastic body in response to the fluid dynamic force are carried out by using the model. It is found that the proposed elastic body model could be useful for investigating the mechanism of the deformation of moving elastic shell.
