Abstract:
Unsteady viscous flows over gliding flap of multi-element airfoils are simulated and studied by using moving overlapped grids and the dual-time stepping method. In order to verify the numerical method, pressure distributions of multi-element airfoils in a steady case are calculated and compared with experimental data. Effects of oscillation amplitudes and frequencies on drags, lifts and moments of the multi-element airfoils are analyzed with unsteady simulations for different gliding velocity of the flap. The obtained results are useful in the design of motion of the flap.
Key words: moving overlapped grids; dual-time stepping method; Navier-Stokes equations
