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 …

Trailing-edge serrations are add ons retrofitted to wind-turbine blades to mitigate turbulent
boundary-layer trailing-edge noise. This manuscript studies the physical mechanisms …

Airflow-induced noise prediction and reduction is one of the priorities for both the energy
and aviation industries. This review paper provides valuable insights into flow-induced noise …

The hydrodynamic and acoustic fields for a NACA 0018 with solid and porous trailing edge
inserts are investigated. The porous inserts, covering 20% of the chord, are manufactured …

Aeroacoustic noise is a major concern in wind turbine design that can be minimized by
optimizing the airfoils that shape the rotating blades. To this end, we present a framework for …

The three-dimensional flow field over the suction side of a NACA 0018 airfoil with trailing-
edge serrations was studied by means of time-resolved tomographic particle image …

This paper presents a comprehensive analytical approach to the modelling of wall-pressure
fluctuations under a turbulent boundary layer, unifying and expanding the analytical models …

Trailing edge serrations designed to reduce airfoil self-noise are retrofitted on a NACA 0018
airfoil. An investigation of the boundary layer flow statistical properties is performed using …

The turbulent flow over a porous trailing edge of a NACA 0018 airfoil is experimentally
investigated to study the link between the hydrodynamic flow field and the acoustic …

Open-jet, hard-wall, and hybrid test section configurations are typically used in wind tunnel
tests, aiming to represent the ideal free-flight condition. Each test section type requires …
