Abstract
The electo-hydrodynamic (EHD) spraying is an atomization process that involves an instability of liquid interface owing to the electrostatic force. The instability of this type is produced due to an electric charge overcoming the surface tension force of the liquid. The EHD spraying involves various modes, and our attention is focused on a cone-jet mode, in which minute and homogeneous droplets are produced. Our purpose is to produce a model blood cell by using the cone-jet mode EHD spraying. But the mechanism of the cone-jet mode is not understood very well. Therefore, at first, we examined the influence of the electrode polarity on sprayed droplets.
