Abstract

A series of flow control experiments were carried out in order to reconcile some of the observations made about enhancement of lift by periodic excitation. The relative merits of flow control were assessed in comparison with conventional design techniques to establish the best strategy to utilize flow control. The frequency of choice, its effect on the pressure distribution, and the optimum location of the actuation and its amplitudes are specifically discussed. The results of periodic excitation were also compared to results generated using steady blowing or suction.
