Acoustically Informed Statistics for Wave-Packet Models

What is it about?

Recent tools for jet noise prediction use modeled wavepacket structures that approximate coherent flow features in the jet. These wavepackets are not yet defined in a unique way, nor do they necessarily represent radiated acoustic waves in all scenarios. We develop a universal variable for wavepacket structures in turbulent jets, that efficiently captures the radiated sound component. This is then used to model sound emissions from a subsonic jet.
