    Abstract

    Experiments have been performed at low speeds documenting certain broad aspects of hysteresis on a mildly13; swept wing under high-lift conditions. Aerodynamic load measurements were carried out at two values of incidence,13; 10.5 and 15.5 deg, and flap deflections of 20 and 30 deg, essentially under quasi-steady conditions. Two-dimensional13; particle image velocimetry (PIV) was utilized to measure the mean velocity vector field in the rear part of the wing13; and flap. These velocity measurements have revealed the complex nature of separated flows on the wing and flap.13; Also, in general, the slot flow angle determined by geometric considerations is very different from those actually13; inferred from PIV measurements.
