Dynamics of Vortices Shed from an Elastic Heaving Thin Film by Fluid-Structure Interaction Simulation

摘要

The flow field around a moving body is treated as a fluid-structure interaction, and such phenomena consist of a series of moving elastic deformations of the body, vortex generation, growth, and development. In particular, the flow fields around thin materials have attracted attention due to their importance with respect to the development of micro air vehicles, for example. In this paper, we simulate the fluid-structure interaction of flow fields around an elastic heaving thin film using ANSYS 12.1/ANSYS CFX 12.1. The purpose of this study is to clarify the development of vortex flow structures in the wake of elastic heaving thin films.
