Viscous/inviscid-interaction procedure developed for computation of two-dimensional flow of air about airfoil, angle of attack of which oscillates at high amplitude. Purpose of procedure to study flow effects in dynamic stall. Bulk of flow treated as inviscid, while effects of viscosity treated only on surface of airfoil and in boundary layer. Inviscid part of flow simulated via time-marching, unsteady-subsonic-flow panel method incorporating appropriate distributions of unsteady surface and wake singularities.
