The concept of using an array of vortex-generating jets to prevent or delay boundary layer separation is well established and understood to rest on the resulting increase in momentummixing,which “energizes” the near-wall layer, thus enhancing the ability of the boundary layer to resist the influence of an adverse pressure gradient. As a special form of vortex-generating jets, synthetic jets have received a great deal of research attention in thelast two decades, due to their potential promises of delivering flow separation control for aircraft applications with zero net mass flux and the relative ease in being integrated in microelectromechanical systems (MEMS) through micro-fabrication (Gad-El-Hak 2000; Glezer and Amitay 2002; Tang et al. 2007; Zhong et al. 2007; Kotapati et al. 2010).
