Short abstract: Two closed-loop feedback controllers based on PID and on full state-feedback were developed for high amplitude coefficient of lift tracking to expand the control capability of a pitching flat plate beyond the point of attached flow. All experiments were conducted at the University of Dayton Water Tunnel (UDWT) at a Reynolds number of 54,000.

Short abstract: The flow field around a -controlled harmonically pitching flat plate was characterized using Particle Image Velocimetry (PIV). Analysis of the flow field, namely the growth and evolution of the leading-edge vortex (LEV) and other flow features were compared for a -controlled pitching flat plate across different reduced frequencies and amplitudes.

Short abstract: Discrete vortical gusts with different strengths and trajectories were generated and characterized using Time Resolved Particle Image Velocimetry (TR-PIV) in the University of Dayton Water Tunnel (UD-Wat). The discrete vortical gusts were generated by rapidly pitching a flat plate about its quarter chord.

Short abstract: The open and closed-loop response of a wing to discrete vortical gusts of differing strengths was characterized using Time Resolved Particle Image Velocimetry (TR-PIV) in the University of Dayton Water Tunnel (UD-WaT). Discrete vortical gusts were generated by rapidly pitching a flat plate gust generator upstream of the wing.

Short abstract: The necessity of understanding and analyzing the flow field characteristics has prompted researchers to strive for more precise tools and systems to enhance the accuracy of flow velocity measurements. We propose in this paper the noise-robust Particle Event Velocimetry (PEV), which is a particle-level estimate of the flow field based on the analysis of individual seed particles observed and tracked using event-based camera.
