Destabilization of sprays in the cone-jet mode by electrical discharges on the injet

Electrical and granulometric measurements were carried out to examine the effect of electrical discharges on the size distribution of liquid jets. It was shown that the transient visible modification of the cone volume leads to the production of bigger droplets ranging from 50 μm to 200 μm. It was also found that, to stabilize the spraying process it is necessary to define the starting point of the electronic avalanches in order to identify the direction of the electric discharge and the field component to be reduced.
