Unsteady aerodynamic loads were measured on a NACA 0021 airfoil during rapid flap deflections. Typical dynamic-stall effects like an overshoot in lift, drag, and pitching moment have been observed the absence of active flow control. Final flap-deflection angles rate their deflections varied at constant angle attack. Stall prevention or delay was achieved by fluidic actuators that generated discrete sweeping jets over upper surface deflected simple flap. Static experiments proved...
View Video Presentation: https://doi.org/10.2514/6.2023-2310.vid The benefits of Active Flow Control (AFC) become limited when trying to apply it a preexisting geometry that cannot be altered. In order showcase the full potential AFC, and allow technology more prominent in vehicle designs, needs considered during conceptual design phase allowed help shape vehicle's geometry. A current limitation is Computational Fluid Dynamics (CFD) wind tunnel testing are too slow costly rapidly evaluate...
Unsteady aerodynamic loads on a NACA 0021 airfoil during rapid flap deflections were investigated. Typical dynamic stall effects like an overshoot in lift, drag, and pitching moment have been observed. Flap deflection angle speed varied while the of attack remained constant at = 0 . To prevent accompanying detrimental behavior, fluidic actuators generating discrete sweeping jets integrated into simple airfoil. Initial experiments various angles incidence but proved that these can flow...
A previously healthy 18-year-old girl was evaluated at an urgent care center for a threeday history of sore throat, fever, nausea, vomiting, diarrhea, and myalgias; the diagnosis influenza made that time.Four days later, she presented to our Emergency Department with left sided neck pain swelling, productive cough, worsening dyspnea, pleuritic chest pain.On examination her temperature 36.9 C, heart rate 142 beats per minute, respiratory 18 breaths minute.She had enlarged tonsils without...
