Abstract

Detailed measurements of pressure and velocity characteristics are reported for the attached flow on a trailing flap and in its downstream asymmetric wake. The results indicate that the flow over the flap is subjected to an adverse pressure gradient. Near the trailing edge, an inflection point develops in the streamwise velocity profile and the flow approaches intermittent separation. The wake is asymmetric with a destabilizing curvature on the suction side and a stabilizing curvature on the pressure side. Streamwide variations in the near wake are primarily confined to the inner layer, and further downstream the mean velocity and turbulence quantities attain self-similar profiles. Nonequilibrium effects are present in the near wake and imply that mixing length models are not appropriate.
