| Abstract: | Transient aerodynamic response of an airfoil to a rapidly deploying spoiler is numerically investigated by solving two-dimensional unsteady compressible Navier-Stokes equations.The spoiler moving relative to a stationary airfoil is treated by a dynamic overset grid method.The mechanism of the adverse lift because of the rapidly deploying spoiler is analyzed.As a primary purpose,the effect of angle of attack and height of spoiler on the unsteady flows are investigated. |
