A 3D printed acoustic metamaterial liner to reduce low-frequency aeroengine noise
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)As the level of air travel continues to increase, so too does the demand for better noise-reduction technologies for aircraft. The environmental noise produced by aircraft has been shown to have a significant adverse effect ... -
Spanwise structure of wall pressure on a cylinder in axial flow
(American Institute of Physics, 1999)The spanwise structure of wall pressure fluctuations was measured in an axtisymmetric turbulent boundary layer on a cylinder parallel to the mean flow at a momentum thickness Reynolds number of 2530 and a boundary layer ... -
TEENI-Turboshaft Engine Exhaust Noise Identification
(2010)The TEENI project is an FP7 level 1 (Theme 7 ? Transport) 1st Call EU-funded project. It focuses on Helicopter Engine Exhaust Broadband Noise, and tries to identify the origin of this noise from external measurements only. ...
