Description Acoustic metamaterials represent an emerging field of research for sound control and noise attenuation, thanks to their ability to manipulate acoustic waves in unconventional ways. Acoustic metasurfaces, a subclass of metamaterials, are thin structures designed to interact with sound waves through reflection, absorption and transmission mechanisms. However, their behavior in the presence of complex flows, such as turbulent ones, remains poorly understood. The presence of a variable velocity and pressure field, characteristic of aerodynamic flows, can significantly influence the operating properties of these surfaces, limiting their effectiveness or, on the contrary, opening up new application possibilities.
This work aims to deepen the numerical study of the interaction between turbulent flows and acoustic metasurfaces, with the aim of understanding how turbulence and pressure field fluctuations influence their noise attenuation capacity.
