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 effect of thermodynamic and transport properties on the convective-to-absolute
transition in heated round jets is investigated with the spatio-temporal linear stability theory …

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 …

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

We present a numerical study of the structure and stability of laminar isothermal flows
formed by two counterflowing jets of an incompressible Newtonian fluid. We demonstrate …

Opposed-jet flows have been shown to provide a valuable means to study a variety of
combustion problems, but have been limited to either laminar or modestly turbulent …

Purpose The purpose of the paper is to summarize recent achievements and suggest further
research directions in numerical studies of round free jets with particular attention on the …

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 …

An axisymmetric heated air-jet discharging into cold stagnant air is investigated
experimentally. Attention is focussed on the transitional regime in which the initial shear …

Direct numerical solutions of the incompressible Navier–Stokes equations, under the
Boussinesq approximation, for the temporal evolution of a jet-like flow have been analyzed …
