Measurements of turbulent flow behind a wing-body junction

Wind tunnel measurements have been obtained for the turbulent shear flow behind a wing mounted on a flat plate at 30-deg angle-of-attack, giving attention to such physical aspects of the flow as the skin-friction coefficient and pattern, the static pressure coefficient, and two mean velocity components. No evidence is found of the presence of a second tornado vortex, perhaps due to the attached flow conditions on the windward side of the wing, where flow separation from the trailing edge did not lead to a sufficiently large reversed-flow region.
