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…
Absolute instability in shock-containing jets
Petrônio A. S. Nogueira, Peter Jordan, Vincent Jaunet +3
We present an analysis of the linear stability characteristics of shock-containing jets. The flow is linearised around a spatially periodic mean, which acts as a surrogate for a me…
Including acoustic modes in the vortex-sheet eigenbasis of a jet
Matteo Mancinelli, Eduardo Martini, Vincent Jaunet +1
Vortex-sheet models of jets are widely used to describe the dynamics of modes, such as the Kelvin-Helmholtz instability and guided acoustic waves. However, it is seldom pointed out…
Self-similar mechanisms in wall turbulence studied using of resolvent analysis
U. Karban, E. Martini, A. V. G. Cavalieri +2
Self-similarity of wall-attached coherent structures in a turbulent channel at is explored by means of resolvent analysis. In this modelling framework, coherent structur…
Resolvent-based modeling of turbulent jet noise
Ethan Pickering, Aaron Towne, Peter Jordan +1
Resolvent analysis has demonstrated encouraging results for modeling coherent structures in jets when compared against their data-educed counterparts from high-fidelity large-eddy…
