When the pressure fluctuations caused by turbulence vorticity in the boundary layer are
scattered by a sharp trailing edge, acoustic energy is generated and propagated to the far …

This paper proposes a novel trailing-edge treatment to reduce trailing-edge noise. Prior
studies showed that both porous materials and wavy trailing edges have decent trailing …

This paper presents the investigation of airfoil turbulent boundary-layer trailing-edge noise
reduction using a parametric airfoil design. The airfoil design tool performs a parametric …

This paper uses Reynolds-averaged Navier–Stokes computational fluid dynamics to study
trailing edge noise reduction with 3-D finlets. Reynolds-averaged Navier–Stokes …

This paper proposes a novel trailing-edge treatment to reduce airfoil self-noise: a serration–
finlet configuration. According to the current literature, while serrations are good at reducing …

The purpose of this research is to find the optimal shape with lowest trailing-edge noise
level. In the present paper, the airfoil geometry is morphed using the parametric airfoil …
