Abstract

The influences of structure parameters of airfoil with local flexible structure on the performance and flow structure under low Reynolds number are investigated numerically. The local flexibility model is established

the unsteady fluid-structure interaction is simulated by arbitrary Lagrangian-Eulerian method(ALE)and characteristic-based split(CBS)scheme with dual time step. The results indicate that there is an optimal range of oscillation frequency and amplitude

at which the airfoil lift can be enhanced remarkably. With proper structure parameters

such as small elasticity modulus and structural damping

the coupling between structure and fluid leads to large amplitude oscillation to change the flow structure and to enhance lift. For the cases with high lift enhancement

the structure oscillation facilitates changing flow pattern and reducing separated region to suppress flow separation and enhance airfoil lift.
