Francesco Avallone studied Aerospace Engineering at the University of Naples Federico II where he obtained also the PhD. His research interest focus on application of computational aeroacoustics to investigate the noise generation mechanisms and noise reduction solutions for wind energy and aeronautical applications. He is currently working on acoustic liners, porous materials and urban wind turbines on projects sponsored by Clean Sky 2, NWO and AARC.

Daniele Ragni graduated in Thermo-Mechanical Engineering at the Polytechnic University of Marche (2007). Obtained the Ph.D. in 2012 (Faculty of Aerospace Engineering TU Delft) and joined TU Delft at the section of Wind Energy in the AWEP Department in the same year.

Assistant professor of Aerodynamics and recipient of NWO-STWs Thames (2016), IPER-MAN (2017), Marie Curie ETN SMART-ANSWER (partner, 2016) and European Project ARTEM (partner, 2016). In his current projects across wind energy and propulsion he supervised/s about 10 PhDs.

The research interests cover the development of experimental aeroacoustics (PIV) and its applications to rotors in low/high-speed. His background in wind energy and propulsion is engaging him in the extension of PIV-based pressure reconstruction in wind turbine and aircraft propeller blades for academic and industrial aerodynamics research. Notable developments are the usage of porous open-foams for the abatement of aeroacoustic noise scattering by pressure fluctuations and his studies on new serrated devices for wind-turbine noise reduction.
