Coherence decay and its impact on sound radiation by wavepackets
AVG Cavalieri, A Agarwal - Journal of Fluid Mechanics, 2014 - cambridge.org
Wavepackets obtained by a linear stability analysis of the turbulent mean flow were shown
in recent works to agree closely with some relevant statistics of turbulent jets, such as power …
