Marine anthropogenic noise has increased significantly over the past few decades, and a
growing body of research is highlighting the negative impacts this is having on marine eco …

Owls are an order of birds of prey that are known for the development of a silent flight. We
review here the morphological adaptations of owls leading to silent flight and discuss also …

An aerofoil leading-edge profile based on wavy (sinusoidal) protuberances/tubercles is
investigated to understand the mechanisms by which they are able to reduce the noise …

This paper presents the results of a detailed experimental investigation into the effectiveness
of sinusoidal leading edge serrations on aerofoils for the reduction of the noise generated by …

A lattice-Boltzmann method has been employed to study the aeroacoustics and
aerodynamics of airfoils equipped with leading edge treatments, namely the porous leading …

An analytical model is developed for the prediction of noise radiated by an aerofoil with
leading-edge serration in a subsonic turbulent stream. The model makes use of Fourier …

A detailed experimental study on the aerodynamic performance and noise emission of
airfoils and fan blades with permeable leading edges under disturbed inflow conditions was …

This study utilizes a hybrid aeroacoustic model to investigate how airfoils with spanwise
wavy geometries can be used to reduce trailing-edge noise alongside improving the …

This paper is a predominantly experimental study into the use of porosity located
downstream of an aerofoil leading edge for the reduction of turbulence interaction noise …

The low-pressure turbine (LPT) has become a potential noise source for future ultra-high by-
pass ratio engines. In this paper, the feasibility and mechanism of wavy leading edge (WLE) …
