abstract = {<p style="text-align: justify;">A localized flexible airfoil at low Reynolds numbers is modeled and the
aerodynamic performance is analyzed numerically. With characteristic based split
scheme, a fluid solver for two dimensional incompressible Navier-Stokes equations is
developed under the ALE framework, coupled with the theory of shallow arch, which
is approximated by Galerkin method. Further, the interactions between the unsteady
flow and the shallow arch are studied in detail. In particular, the effect of the self-excited vibration of the structure on aerodynamic performance of the airfoil is investigated deeply at various angles of attack. The results show that the lift-to-drag ratio
has been increased greatly compared with the rigid airfoil. Finally, the relationship
between the self-excited vibration and the evolution of the flow is analyzed using FFT
tools.</p>},
