Abstract

The addition of weak, steady blowing to periodic perturbations of comparable momentum had detrimental effect on the control of separation over a deflected flap. The strength of the steady blowing had to surpass a certain threshold in order to overcome the damage. The purpose of this study was to investigate this effect and attempt to explain it. The experiments were carried out over a deflected, straight flap. Instantaneous pressure measurements were made over the entire surface while concomitantly two components of velocity were measured above it by using a particle image velocimeter (PIV).
