III. Conclusion Several conclusions can be drawn from the study. 1) A periodical surface ow control can produce a three-dimensionalperturbationthat leads to the formationof streamwisevortical ow structuresin the separatedshear layer.Thoughsuctionwas used in this study, boundary-layercontrols in general should achieve the same effect when applied in a similar fashion. 2) The vortical structures cause a normally separated ow to reattach. 3) The control is most effective when applied near and upstream of the natural separation. 4) The control device size, as measured in this particular case by the combinationof suction hole diameter, hole number density, and associated porosity, is small. 5) Similar results are obtained over different control patterns, indicating a broadband instability.
