Diesel fuel jet with laminar inflow conditions. These movies were produced by Anthony Leboissetier with the 2D SURFER
code.
Diesel fuel jet with turbulent inflow conditions With turbulent inlet conditions, the jet atomizes rapidly, indicating that the instability is a noise amplifier. A rather small level of noise is sufficient to trigger the instability,
and it is even likely that recirculating vortices could also trigger instability.
Dual-jet liquid-gas jet case with high resolution and turbulent inflow conditions, vorticity map.
Sheared two-phase
layer produced by Jie
Li. This movie was produced with the 3D
SURFER code : this type of instability is typical of the atomization process we study.
Droplet falling on a liquid layer.
This movie and the following one were coproduced with the 3D
SURFER code and the CRS4 research
center.
Pinching
