We study the velocity fields of unforced, high Reynolds number, subsonic jets, issuing from
round nozzles with turbulent boundary layers. The objective of the study is to educe …

Coherent turbulent wave-packet structures in a jet at Reynolds number 460 000 and Mach
number 0.4 are extracted from experimental measurements and are modeled as linear …

Gudmundsson and Colonius (J. Fluid Mech., vol. 689, 2011, pp. 97–128) have recently
shown that the average evolution of low-frequency, low-azimuthal modal large-scale …

Installed jet noise is studied by means of a simplified configuration comprising a flat plate in
the vicinity of a round jet. The effects of Mach number, jet-plate radial distance, and trailing …

Linear instability waves, or wavepackets, are key building blocks for the jet-noise problem. It
has been shown in previous work that linear models correctly predict the evolution of …

Wavepackets obtained by a linear stability analysis of the turbulent mean flow were shown
in recent works to agree closely with some relevant statistics of turbulent jets, such as power …

In the method of monitoring the liquid level based on ultrasonic impedance, the near-field
effect can seriously affect the validity of the results. In this paper, we explore the factors …

The link between jet-installation noise and the near-field flow features of the corresponding
isolated jet is studied by means of lattice-Boltzmann numerical simulations. The …

An experiment has been performed in order to provide support for wave-packet jet-noise
modeling efforts. Recent work has shown that the nonlinear effects responsible for the two …

Three methods are considered for estimating the downstream evolution of wavepackets in
turbulent jets based on upstream measurements. The parabolised stability equations are …
