Since the experiments of Monkewitz et al.(J. Fluid Mech. vol. 213, 1990, p. 611), sufficiently
hot circular jets have been known to give rise to self-sustained synchronized oscillations …

The self-sustained formation of synchronized ring vortices in hot subsonic jets is investigated
by direct numerical simulation of the axisymmetric equations of motion. The onset of global …

The onset of self‐excited or limit‐cycle oscillations in an axisymmetric hot jet is studied
experimentally as the jet density is systematically decreased below the value at which …

Spatially extended open flows may be classified according to their dynamical behavior.
Either they may be easily manipulated by external excitations for example, a forcing fixed in …

This paper presents experimental results on the nonlinear phase locking present in the
resonant growth of unstable modes in the shear layer of an axisymmetric jet. The initial …

The linear stability dynamics of incompressible and compressible isothermal jets are
investigated by means of their optimal initial perturbations and of their temporal …

An axisymmetric hot-air jet discharging into cold ambient air is investigated experimentally.
We consider the transitional regime, that is, Reynolds numbers at which the jet is initially …

This paper is concerned with a dominant feature of transitional separated flows, namely their
ability to develop and maintain self-sustained oscillations. Experiments performed with an …

The modal distributions of coherent structures evolving near the nozzle of a circular jet are
considered. The effects produced on the instability modes by transverse curvature, flow …

In low-density axisymmetric jets, the onset of global instability is known to depend on three
control parameters, namely the jet-to-ambient density ratio. This scaling, which is insensitive …
