Abstract
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 strategies. A hybrid semi-empirical prediction model
has recently been developed based on the instability-wave-scattering mechanism.
However, its validity and accuracy remain to be tested. To do so, in this paper
we carry out a systematic installed jet-noise experiment in the laboratory
using a flat plate instead of an aircraft wing. We show that reducing
