Teruna, C. (author), Avallone, F. (author), Ragni, D. (author), Rubio Carpio, A. (author), Casalino, D. (author)Lattice Boltzmann simulations were carried out to investigate the noise mitigation mechanisms of a 3-D printed porous trailing-edge insert, elucidating the link between noise reduction and material permeability. The porous insert is based on a unit cell resembling a lattice of diamond atoms. It replaces the last 20 % chord of a NACA 0018 at...journal article 2021
