My name is Daniele Ragni, I graduated in Thermo-Mechanical Engineering at the Polytechnic University of Marche in 2007.   I obtained my Ph.D. in 2012 at the Faculty of Aerospace Engineering in TU Delft and after that I joined the newly formed TU Delft AWEP Department at TU Delft in the combined sections of Wind Energy and Flight Performance and Propulsion.
Together with my colleagues Francesco Avallone and Damiano Casalino I founded the Aeroacoustic Team of TU Delft which now counts more than 30 enthusiastic researchers at the PhD, PostDoc and Assistant Professor level.  In the last few years, I have specialized in Aeroacoustics with a focus on fundamental physics and experimental applications.
I had the honor of getting funded the first grants in noise mitigation studies at TU Delft and together with my Francesco Avallone and Damiano Casalino we now carry on projects across wind energy and propulsion:

  •  rotor noise reduction including propellers, ducted fans, wind turbines blades and turbofan engines;
  • experimental measurement techniques for dense reconstruction of velocity fields with aeroacoustic applications;
  • active and passive turbulence modification devices for aeroacoustic purposes.
