Resolvent-based tools for optimal estimation and control via the Wiener-Hopf formalism
Eduardo Martini, Junoh Jung, André V. G. Cavalieri +2
The application of control tools to complex flows frequently requires approximations, such as reduced-order models and/or simplified forcing assumptions, where these may be conside…
Wavepacket modulation in shock-containing jets
Petrônio A. S. Nogueira, Hamish W. A. Self, Aaron Towne +1
We propose a new approach to predict the modulation of wavepackets in shock-containing jets. With a modelled ideally expanded mean flow as input, an approximation of the shock-cell…
Reflection and transmission of a Kelvin-Helmholtz wave incident on a shock in a jet
Matteo Mancinelli, Eduardo Martini, Vincent Jaunet +3
Screech tones in supersonic jets are underpinned by resonance between downstream-travelling Kelvin-Helmholtz waves and upstream-travelling acoustic waves. Specifically, recent work…
Resolvent-based estimation of space-time flow statistics
Aaron Towne, Adrian Lozano-Duran, Xiang Yang
We develop a method to estimate space-time flow statistics from a limited set of known data. While previous work has focused on modeling spatial or temporal statistics independentl…
Jet-edge interaction tones
Peter Jordan, Vincent Jaunet, Aaron Towne +4
Motivated by the problem of jet-flap interaction noise, we study the tonal dynamics that occur when a sharp edge is placed in the hydrodynamic nearfield of an isothermal turbulent…
