Noise Reduction Mechanisms of an Airfoil with Trailing Edge Serrations at Low Mach Number
Applied Sciences, 2019 Trailing-edge serrations have proven to be valid applications of trailing edge noise mitigation for an airfoil, while the physical noise reduction mechanism has not been adequately studied. We performed simulations employing Large-eddy simulation and the

Identifying global hotspots of avian trailing-edge population diversity
Global Ecology and Conservation, 2020 Climate change is causing the ranges of many species to shift poleward and to higher elevations. Trailing-edge populations near the low-latitude edge of a shifting range are predicted to be at high risk of climate-induced extinction, but conservation ...

Reduction of airfoil trailing edge noise by trailing edge blowing [PDF]
Journal of Physics: Conference Series, 2014 The paper deals with airfoil trailing edge noise and its reduction by trailing edge blowing. A Somers S834 airfoil section which originally was designed for small wind turbines is investigated. To mimic realistic Reynolds numbers the boundary layer is tripped on pressure and suction side. The chordwise position of the blowing slot is varied.

Diffraction by a half-plane in a moving fluid [PDF]
, 2005 In the following work we solve the problem of the diffraction of a plane sound wave by an impedance half-plane in a moving fluid. Expressions for the total far field are derived for both the leading edge and trailing edge situations. In the trailing edge

Bioinspired Trailing-Edge Noise Control [PDF]
AIAA Journal, 2015 Strategies for trailing edge noise control have been inspired by the downy canopy that covers the surface of exposed flight feathers of many owl species. Previous wind tunnel measurements demonstrate that canopies of similar characteristics can reduce pressure fluctuations on the underlying surface by as much as 30dB, and significantly attenuate ...
