Abstract

It is experimentally demonstrated that electrostatic polarization forces can in principle be utilized in generating fine bubbles and droplets, despite the lack of charge carriers that have traditionally been thought to be necessary for successful electrostatic spraying. Under the condition that the permittivity of the dispersed phase is lower than that of the continuous phase, such as when gas bubbles are sprayed into insulating liquids, the spraying behavior is regular and easy to control. If the permittivity of the dispersed phase is higher than that of the continuous phase, such as when insulating liquids are sprayed into gases, the spraying behavior lacks regularity and further research is needed before pure polarization forces can find significant applications in practical processes.
