Spectral analysis of jet turbulence

16 Nov 2017Oliver T. SchmidtAaron TowneGeorgios RigasTim ColoniusGuillaume A. Brès

Informed by LES data and resolvent analysis of the mean flow, we examine the structure of turbulence in jets in the subsonic, transonic, and supersonic regimes. Spectral (frequency-space) proper orthogonal decomposition is used to extract energy spectra and decompose the flow into energy-ranked coherent structures... (read more)
