Published in 2018 at "Applied Acoustics"

DOI: 10.1016/j.apacoust.2018.04.040

Abstract: Abstract In this paper, high-speed impulsive noise radiated from helicopter rotors in hover and forward flight is computed by using a convected FW-H equation in the frequency domain with a rotating permeable data surface. Compared… read more here.

Published in 2017 at "Journal of Sound and Vibration"

DOI: 10.1016/j.jsv.2017.05.016

Abstract: Abstract Empirical models such as the Eldred standard model are commonly used for rocket noise prediction. Such models directly provide a definition of the Sound Pressure Level through the quadratic pressure term by uncorrelated sources.… read more here.

Published in 2021 at "Australian Journal of Mechanical Engineering"

DOI: 10.1080/14484846.2021.1950352

Abstract: small scale VAWTs are erected in built up areas while in these locations they will be inherently close to people. Therefore, the noise radiated from a VAWT is very significant to make an investigat... read more here.
