Three component velocity measurements in an upper surface blowing configuration
In four recent papers, results of an experimental investigation of a freely expanding coflowing jet as well as a three dimensional wall jet have been presented. A flat plate and a curved wall surface modelling a wing-flap combination in a high lift V/STOL configuration have been documented as to their effects on the flow field. The ratio of the jet exit plane velocity to the free stream velocity was varied from 5.1 to 10.9 to 1. This report continues the documentation of the three dimensional wall jet with special emphasis on the vertical and lateral mean and fluctuating velocities. Additionally, boundary layer profiles over both the flat plate and the flap are presented.
