The production of a liquid spray can be summarized as the succession of the following three
steps; the liquid flow ejection, the primary breakup mechanism and the secondary breakup …

The near-field breakup and interaction of a hollow-cone liquid sheet with coannular swirling
air flow have been examined using high-speed diagnostics. Time-resolved PIV (particle …

This experimental study is devoted to the influence of the air and liquid thicknesses on an air-
blasted atomizer. The flow configuration corresponds to a planar liquid sheet sheared on …

The cellular breakup phenomenon is investigated experimentally for a planar liquid sheet
from an air-blast nozzle. The dominant sinuous wave growing spatially downstream forms …

This paper discusses the fundamental mechanisms of vortex–droplet interactions leading to
flow distortion, droplet dispersion and breakup in a complex swirling gas flow field. In …

Spray formation in ambient atmosphere from gas-centered swirl coaxial atomizers is
described by carrying out experiments in a spray test facility. The atomizer discharges a …

We measure experimentally the frequency of the large-scale instability developing on a
liquid jet incompletely atomized by a parallel fast gas stream. We demonstrate that this …

Liquid injection systems play a key role in the control of flame stability and reduction of
pollutant emissions in aircraft engines. However, the disintegration process of the liquid fuel …

In this experimental study, a thin annular moving water sheet is placed between two annular
co-flowing air streams. The shear at the interface gives rise to Kelvin–Helmholtz type …

L'objet de cette thèse a été de développer un code de calcul pour la simulation
d'écoulements diphasiques de fluides non miscibles, incompressibles et isothermes afin de …
