Abstract
A class of high amplitude and high bandwidth actuators called localized arc filament plasma actuators (LAFPAs) have recently been developed at OSU and used for control of high-speed and high Reynolds number jets. The control included successful noise mitigation in a Mach 0.9 jet and mixing enhancement (and very preliminary results for noise mitigation) in a Mach 1.3 ideally expanded jet. The control relies on high bandwidth of the actuators and excites various instabilities in the jet to achieve the goal of mixing enhancement or noise mitigation. The proposed Phase I work will explore the effectiveness of this technology in more practical supersonic exhaust jets operating with various flow regimes (i.e. ideally-, over-, and under-expanded) and high temperature. Phase I work will pave the way for detailed parametric study of the control issues to achieve maximum noise mitigation in Phase II, where we will also explore integration and commercialization issues.
