Noise reduction mechanisms of an open-cell metal-foam trailing edge

Journal of Fluid Mechanics, 2020
Open-cell porous materials have been reported as a promising concept for mitigating turbulent boundary-layer trailing-edge noise. This manuscript examines the aeroacoustics of a porous trailing edge to study its noise reduction mechanisms.
