Supersonic jets, particularly shock-containing jets, often exhibit high-intensity, discrete-
frequency acoustic tones. These tones are the signature of an aeroacoustic resonance loop …

In the last decade, many research groups have reported predictions of jet noise using high-
fidelity large-eddy simulations (LES) of the turbulent jet flow and these methods are …

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 …

Experimental evidence is provided to demonstrate that the upstream-travelling waves in two
jets screeching in the A1 and A2 modes are not free-stream acoustic waves, but rather …

A shock-capturing methodology is developed for non-linear computations using low-
dissipation schemes and centered finite differences. It consists in applying an adaptative …

The interaction between various wave-like structures in screeching jets is considered via
both experimental measurements and linear stability theory. Velocity snapshots of …

Round jets originating from a pipe nozzle are computed by large-eddy simulations (LES) to
investigate the effects of the nozzle-exit conditions on the flow and sound fields of initially …

An axisymmetric jet at a diameter-based Reynolds number of 1.1× 104 is computed by a
large eddy simulation (LES) in order to investigate its self-similarity region. The LES …

In this paper, the origin and the properties of the oscillation modes in screeching non-ideally
expanded rectangular jets are investigated using compressible implicit LES of rectangular …
