摘要
Abstract
The study of fluid-structure interaction of thin plate has broad applications in nuclear reactor fuel assembly and the wind turbine blade. Fluid-structure interaction analysis was based on the interaction between unsteady flow and the thin plate＇s vibration. The characteristics of the plate＇s vibration and the unsteady flow behaviors around the plate were obtained. Results reveal that under the impact of stable flow, the thin plate vibrates at its first-order natural frequency and the vibration is self-excited vibration. At the same angle of attack, fluid-structure interaction becomes more severe with the increase of flow velocity. The comparison between the results without considering fluid-structure interaction and the results considering fluid-structure interaction was made. The comparison results show that the average aerodynamic force is larger without the consideration of fluid-structure interaction. The vibration of the thin plate restrains the formation of eddies. It can also remain the plate＇s attached flow and delay the flow separation.关键词
