Conference Paper
View Video Presentation: https://doi.org/10.2514/6.2022-3330.vid Phononic materials have rich frequency-dependent characteristics that can be designed into their geometry. These characteristics can open up new avenues for passively controlling flow instabilities with intrinsic frequency content. Recent numerical studies demonstrated the potential o...

View Video Presentation: https://doi.org/10.2514/6.2022-2257.vid Magnetically-guided atmospheric arc devices were applied to provide plasma-excitation to premixed methane-air flames. Researchers have recently applied similar technology to study vortex generation for aerodynamic flow control, and the scaling and driver circuits used for those device...
Conference Paper
A series of experiments were conducted on a quasi-2D S8036 airfoil with a distributed electric propulsion (DEP) system. An overwing ducted fan system was tested with varied thrust angles achieved by deflecting the fan exit flow direction. The DEP system was comprised of five electric fans mounted on the upper surface of the airfoil trailing edge. T...

A novel axisymmetric device with pulsed spark emission was developed as an active flow control alternative to passive vortex generators. The flowfield induced by the actuator was studied in quiescent flow. The current-voltage characteristics and power requirements of the high-voltage circuit that powered the discharge were detailed at different ope...

A novel axisymmetric device with pulsed spark emission was developed as an active flow control alternative to passive vortex generators. The flowfield induced by the actuator was studied in quiescent flow. The current–voltage characteristics and power requirements of the high-voltage circuit that powered the discharge were detailed at different ope...
Article
The current study was conducted to understand flowfield unsteadiness associated with static stall hysteresis on a NACA 0012 airfoil at Rec=1.0×106. Unsteady pressure measurements were acquired to evaluate the performance of the airfoil, and the presence of a hysteresis loop was identified in the vicinity of the airfoil Cl,max. At poststall angles o...
