It is generally recognized that zonal-type methods, based on boundary-layer concepts, lead to very effective procedures for computing viscous flows at high Reynolds numbers. To achieve their full potential, these methods should account for strong-interaction effects that arise at trailing edges. The trailingedge interaction is of particular importance because of its influence on the Kutta condition, leading to large global effects on lift and drag. The present paper deals with the theoretical description of strong viscid-inviscid interaction at the trailing edge of an airfoil, when the boundary layer approaching the trailing edge is a fully developed turbulent flow.
