Raiola, Marco (author), Ragni, D. (author)The present study proposes a data-driven strategy to extract the dynamics of wave-packets from low-speed velocity field measurements. The flow field under study is a subsonic turbulent round jet at Re = 33000, measured over a 20-nozzle-diameters domain in the axial direction using low-repetition-rate planar Particle Image Velocimetry. The...conference paper 2019

Raiola, M. (author), Discetti, Stefano (author), Ianiro, A. (author), Samara, F. (author), Avallone, F. (author), Ragni, D. (author)This study focuses on an active strategy for unsteady-load control by means of a trailing-edge flap. Experiments on a 2D pitching and heaving NACA 0018 airfoil with an actuated trailing-edge flap are performed at a reduced frequency κ = 0.1 in a free-stream flow with Re = 1.3 × 10<sup>5</sup>. The model is equipped with 24 differential...journal article 2018
