Mechanisms of Drop Formation in Continuous Ink-Jets

摘要

In this paper, we present our work on the subtle mechanisms of rupture of a continuous ink-jet submitted to various types of initial disturbances. Several experimental methods such as spectral analysis of signals and digital particle image velocimetry (DPIV) are used to characterize both the evolution of the forced liquid jet from nozzle exit to break-off and the formation of main and satellite drops.
