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 …

The ability of some species of owl to fly in effective silence is unique among birds and
provides a distinct hunting advantage, but it remains a mystery as to exactly what aspects of …

Trailing-edge noise is the dominant contributor to the noise generated by aircraft and wind
turbines. Serrations on the trailing edge play a crucial role in suppressing the aerodynamic …

This study investigates the influence of air blowing on the aerodynamic noise generated by
a flat plate with a blunt trailing edge. The uniform blowing was applied through evenly …

Inspired by the silent flight of the owl, the current work focuses on the reduction of trailing
edge noise using 2D finlets. Overset-Large Eddy Simulations are carried out of two …

Effect of airfoil thickness on onset of dynamic stall is investigated using large eddy
simulations at chord-based Reynolds number of 200 000. Four symmetric NACA airfoils of …

The noise emitted by small wind turbines is one of the main reasons for their poor public
perception for use in urban areas. An optimization study was performed to mitigate the …

Noise reduction is an important development direction for aircrafts and wind turbines. Owl
wings have three unique morphological characteristics (leading-edge serrations, trailing …

The trailing-edge serration that imitates the silent owl wing is used as a flow control method
to suppress the aerodynamic noise generated from the rotating wind turbine blade. Recent …

Bio-inspired design is an innovative design method that uses analogies to biological
systems to develop solutions for engineering problems. It offers a huge potential to produce …
