The purpose of this paper is to characterize and model waves that are observed within the
potential core of subsonic jets and relate them to previously observed tones in the near …

Coherent features of a turbulent Mach 0.9, Reynolds number jet are educed from a high-
fidelity large eddy simulation. Besides the well-known Kelvin–Helmholtz instabilities of the …

Resolvent analysis identifies the most responsive forcings and most receptive states of a
dynamical system, in an input–output sense, based on its governing equations. Interest in …

Three amplification mechanisms present in turbulent jets, namely lift-up, Kelvin–Helmholtz
and Orr, are characterized via global resolvent analysis and spectral proper orthogonal …

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 …

The wetting and dewetting of solid surfaces is ubiquitous in physical systems across a range
of length scales and it is well known that there are maximum speeds at which these process …

This paper presents bifurcation analyses characterising the nonlinear dynamics of fully
developed laminar annular jets with respect to the centrebody diameter is increased …

Abstract 3D optimal forcing and response of a 2D supersonic boundary layer are obtained
by computing the largest singular value and the associated singular vectors of the global …

The generation of discrete acoustic tones in the compressible flow around an aerofoil is
addressed in this work by means of nonlinear numerical simulations and global stability …

The linear global stability of laminar buoyant jets and plumes is investigated under the low-
Mach-number approximation. For Richardson numbers in the range (plume) regimes. A …
