This paper describes the mechanism underpinning modal staging behaviour in screeching
jets. An upstream-propagating subsonic guided-jet mode is shown to be active in all stages …

Guided-jet waves have been shown to close resonance loops in a myriad of problems such
as screech and impingement tones in jets. These discrete, upstream-travelling waves have …

This paper explores the screech closure mechanism for different axisymmetric modes in
shock-containing jets. While many of the discontinuities in tonal frequency exhibited by …

Spatial linear stability analysis is used to study the axisymmetric screech tones generated by
twin converging round nozzles at low supersonic Mach numbers. Vortex-sheet and finite …

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 mean …

The estimation of time-resolved three-dimensional (3D) density fields of an underexpanded
jet at the nozzle pressure ratio of 2.42, a so-called “spatiotemporal super-resolution” was …

The aeroacoustic feedback loops in high-speed circular jets that impinge on a large flat plate
are investigated via acoustic measurements and schlieren visualizations. In the present …

The authors have recently demonstrated that modal staging in screeching jets is governed
by interaction between the Kelvin-Helmholtz wavepacket and one of several peaks in the …

waves involved in the screech resonance loop in rectangular jets is undertaken in this work …

In this paper, the acoustic resonance mechanism for different axisymmetric screech modes
of the underexpanded jets that impinge on an inclined plate is investigated experimentally …
