This paper discusses various noise generation mechanisms in wind turbines and potential
noise reduction techniques. Special emphasis has been laid on reviewing aerodynamic …

This comprehensive review aims to provide a critical overview of the work on tubercles in the
past decade. The humpback whale is of interest to aerodynamic/hydrodynamic researchers …

The humpback whale (Megaptera novaeangliae) is exceptional among the large baleen
whales in its ability to undertake aquabatic maneuvers to catch prey. Humpback whales …

A passive leading-edge treatment based on sinusoidal serrations aimed at reducing
turbofan interaction noise has been recently studied in the framework of a European project …

High-order accurate numerical simulations are performed to investigate the effects of wavy
leading edges (WLEs) on aerofoil–gust interaction (AGI) noise. The present study is based …

The paper is about the sound produced as turbulence impinges on the leading edge of an
airfoil and its reduction by means of either leading-edge serrations (tubercles) or the use of …

A comprehensive numerical investigation is performed to study the aerodynamic
performance and wake development of a NACA0012 airfoil with wavy leading edges (WLE) …

It is well-known that many species of owl have the unique ability to fly silently, which can be
attributed to their distinctive and special feather adaptations. Inspired by the owls …

Powered flight was once a capability limited only to animals, but by identifying useful
attributes of animal flight and building on these with technological advances, engineers …

A hybrid computational aeroacoustics method is applied to investigate the effect of wavy
leading edges on rod–airfoil interaction noise. The flow field is solved by an incompressible …
