Stimulation of a Conductive Liquid Jet Directly Heated by an Electric Current
  DOI :  10.2352/ISSN.2169-4451.2001.17.1.art00065_1  Published OnlineJanuary 2001

This paper presents experiments performed on a conductive liquid jet stimulated by an inner volume heating. The stimulating device consists in a couple of plain stainless steel electrodes located within the channel feeding the nozzle, the liquid flowing through the electrode clearance being heated by Joule effect. By applying an appropriate electrical signal, the stimulating device significantly reduces the jet break-up length and produces a very stable stream of droplets. The break-up length varies semi-logarithmically with the applied electric power. We emphasize on printer applications by performing experiments on typical continuous ink jets of small diameter (∼50 μm). Finally, the physical mechanisms giving rise to the stimulation are briefly discussed.
