Abstract:

By solving the unsteady Euler/Navier-Stokes equation with finite volume method and incorporating the grid velocity to take account of the gust influence, the gust response on a rigid thin airfoil is effectively calculated. After applying this method to simulate two typical cases, i.e., gust leading a step change in airfoil’s angle of attack and the sharp-edged gust, it is shown in results that the calculated lift responses of the airfoil agree well with both the exact theoretical values and the calculated values in references.
