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…
