Abstract
A method is developed to predict the flow characteristics in the near wake region of a jet over a finite chord wing surface of an upper surface blown flap. Transition distributions of mean flow and select fluctuating velocity correlations, within the region immediately downstream of a sharp-edged terminus of a slot nozzle-jet flap, are established using a parabolized form of the time-averaged steady flow Navier-Stokes equations closed with a turbulence kinetic energy model. Numerical solutions, obtained using a finite-element algorithm are presented which quantize the localized large mean flow accelerations and resultant peaks in the distribution of turbulence kinetic energy in the near wake region. Results are verified by comparison to experiment.
