Analysis and prediction of noise from installed subsonic chevron jets
Hasan Kamliya Jawahar, Benshuai Lyu, Mahdi Azarpeyvand
An experiment is conducted to investigate the effects of chevrons on installed subsonic jet noise at a Mach number of 0.5 using the NASA SMC000 (round) and SMC006 (chevron) nozzles…
Analytical Green's function for the acoustic scattering by a flat plate with a serrated edge
Benshuai Lyu
An analytical Green's function is developed to study the acoustic scattering by a flat plate with a serrated edge. The scattered pressure is solved using the Wiener-Hopf technique…
Rapid noise prediction models for serrated leading and trailing edges
Benshuai Lyu, Lorna J. Ayton
Leading- and trailing-edge serrations have been widely used to reduce the leading- and trailing-edge noise in applications such as contra-rotating fans and large wind turbines. Rec…
Temporal stability analysis of jets of lobed geometry
Benshuai Lyu, Ann P. Dowling
A 2D temporal incompressible stability analysis is carried out for lobed jets. The jet base flow is assumed to be parallel and of a vortex-sheet type. The eigenfunctions of this si…
Experimental validation of the hybrid scattering model of installed jet noise
Benshuai Lyu, Ann Dowling
Jet installation causes jet noise to be amplified significantly at low frequencies and its physical mechanism must be understood to develop effective aircraft noise reduction strat…
On the noise prediction for serrated leading edges
Benshuai Lyu, Mahdi Azarpeyvand
An analytical model is developed for the prediction of noise radiated by an aerofoil with leading edge serration in a subsonic turbulent stream. The model makes use of the Fourier…
