| Abstract: |
| The unsteady viscous flow fields around dual flapping airfoils in tandem configurations are simulated by a Navier-Stokes Solver on dynamic deformable hybrid meshes. The variation of aerodynamic forces and power as a function of phase difference and horizontal distance are studied, as well as wing-wing aerodynamics interactions. The results indicate that, when a fore airfoil is flapping with a fixed hind airfoil, the aerodynamic interaction between them is of great benefit to aerodynamic performance at different distances, with weaker effect as distance increasing, howerver. When the fore and hind airfoils are flapping simultaneously, the phase of them has great influence on aerodynamics and whether the interaction benefits aerodynamic performance or not depends on the phase and the horizonal distance. |
