• The present paper concerns with the nonlinear liting-flow phenomenon associated with a thick symmetric two-dimensional body with a large trailing edge angle. For such a body or an airfoil, the lift coefficient has a negative slope near zero angle of attack under some conditions. In the previous report, the existence of the phenomenon was confirmed by the experiments using small airfoil models. In this paper the authors attempt to make a physical explanation for the nonlinear phenomenon that it is caused by a viscid-inviscid interaction effect of a thick streamlined body. Results of the experiment with a large airfoil model are also discussed.
