ABSTRACT
The dynamics governing the atomization processes for excited and free cylindrical liquid jets are here investigated by recording the time evolution of the jet diameter by using a laser extinction technique for successive locations along the jet axis. State portraits are hereafter reconstructed by using the delay coordinates. When the jet is forced at a frequency close to the Rayleigh frequency, a first-return map to a Poincare´ section clearly reveals a phase intermittency for a time evolution of the diameter recorded near the break-up in droplets. Such a behavior is also observed for free jets although the dynamics is slightly diffused by stochastic perturbations. The deterministic behavior is also exhibited by using a statistical symbolic dynamics. © 2000 American Institute of Physics.
