Influence of finite span and sweep on active flow control efficacy
D Greenblatt, AE Washburn - AIAA journal, 2008 - arc.aiaa.org
THE capability and limitations of zero mass-flux active flow control (AFC) are reasonably
well understood in relatively simple two-dimensional flows and on airfoils [1]. Thus, for high …
