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

The global stability of laminar axisymmetric low-density jets is investigated in the low Mach
number approximation. The linear modal dynamics is found to be characterised by two …

The linear amplification of axisymmetric external forcing in incompressible jet flows is
investigated within a fully non-parallel framework. Experimental and numerical studies have …

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 linear impulse response of axisymmetric jets is examined for a family of variable-
temperature profiles typical of the potential core. The influence of jet heating, shear layer …

The present work investigates the local modal and non-modal stability of round jets for
varying aspect ratios α= R/θ, where R is the jet radius and θ the shear layer momentum …

Perturbation wavepackets in a jet, induced by externally applied forcing, are computed from
the linearized equations of motion. An experimentally measured mean flow serves as the …

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 …

This study investigates the stability features of spatially spreading heated jets in the viscous
regime with real gas effects, using both unsteady two-dimensional axisymmetric simulations …

The linear inviscid stability of heated compressible axisymmetric jets is re-examined,
focusing on the impulse response of the flow. The case is of particular interest in which a …
